If the RX/TX LED at the INSYS Modem 56k AC/DC 4.2 does not light up, while you type AT and receive an OK, the reason may be that you are connected to another modem (e.g. with the modem integrated in the laptop or the PC). In this case, check to which interface your INSYS Modem 56k AC/DC 4.2 is actually connected and repeat the test. The INSYS Modem 56k AC/DC 4.2 is successfully installed and ready for operation. 33

Operating Principle INSYS Modem 56k AC/DC 4.2 10 Operating Principle This chapter describes the basis procedures to operate and configure a INSYS Modem 56k AC/DC 4.2. It will also give you an overview of the control elements of the software HSComm. You have two possibilities to operate and configure the INSYS Modem 56k AC/DC 4.2. In general, the INSYS Modem 56k AC/DC 4.2 is configured and operated via AT commands. You can enter these commands yourself with the help of a terminal program and the AT command reference. As an alternative, you can enter the most important functions easily with the help of the configuration software HSComm. 10.1 Operation with the Terminal Program In general, any terminal program may be used. We recommend the program TeraTerm by T. Teranishi. It is available free of cost on the Internet at http://hp.vector.co.jp/authors/va002416/teraterm.html. Configuration and settings of the INSYS Modem 56k AC/DC 4.2 with a terminal program How to configure and operate the INSYS Modem 56k AC/DC 4.2 with a terminal program. The INSYS Modem 56k AC/DC 4.2 is connected to the PC and switched on. A terminal program is installed on the PC. 1. Start your terminal program. 2. Open the serial port, to which you connected the INSYS Modem 56k AC/DC 4.2. COM1 under Windows corresponds to /dev/ttys0 under Linux. 3. Type the character string AT into the terminal program. Complete the entry by pressing the Enter key. Each command input starts with AT und is completed with the Enter key. The INSYS Modem 56k AC/DC 4.2 responds with OK: If the INSYS Modem 56k AC/DC 4.2 does not respond, this may have two reasons: a) The INSYS Modem 56k AC/DC 4.2 is switched off or b) The INSYS Modem 56k AC/DC 4.2 is connected to a different serial port. Check it and repeat step 3. 34 4. Configure the INSYS Modem 56k AC/DC 4.2 with the help of the AT

INSYS Modem 56k AC/DC 4.2 Operating Principle commands. A reference of the AT commands can be found in the chapter "AT Command Reference". 5. Save your entries with AT&W. Not all settings at the INSYS Modem 56k AC/DC 4.2 must be actively stored by entering AT&W. Some settings are automatically saved immediately. We still recommend sending the command AT&W to the INSYS Modem 56k AC/DC 4.2 as your last configuration step to ensure that all settings are stored safely and are available for the next restart. 10.2 Operation with HSComm Modem Use the software HSComm to easily configure the INSYS Modem 56k AC/DC 4.2. HSComm offers an interface for the parameters of the most important AT commands of the INSYS Modem 56k AC/DC 4.2. The operation is mostly selfexplanatory. You can download the software from the INSYS MICROELECTRONICS homepage (www.insys-tec.de). Configuration and settings of the INSYS Modem 56k AC/DC 4.2 with HSComm How to configure the INSYS Modem 56k AC/DC 4.2 with the software HSComm.

INSYS Modem 56k AC/DC 4.2 Functions 11 Functions 11.1 Establishing or Accepting a Data Connection The INSYS Modem 56k AC/DC 4.2 can call another modem via the phone line and establish a data connection. After dialling a phone number, the INSYS Modem 56k AC/DC 4.2 synchronises with the called modem and opens a data connection with the transmission speed, which is currently set at the serial interface. All incoming characters are transmitted to the other (called) modem during the active data connection. Therefore, AT commands are not processed during a connection. The INSYS Modem 56k AC/DC 4.2 must be changed to command mode again using an "Escape sequence" that it processes AT commands again during an active connection. Then, the local INSYS Modem 56k AC/DC 4.2 processes the entered characters as AT commands and does not transmit them to the remote terminal. A remote INSYS Modem 56k AC/DC 4.2 can be changed to command mode during an active data connection using the function "Remote configuration". The INSYS Modem 56k AC/DC 4.2 can accept an incoming connection in the same way. For this, the "application" or the PC with the terminal program at the serial interface must have DTR signalling enabled, otherwise, the INSYS Modem 56k AC/DC 4.2 does not accept the incoming connection. In this case, DTR signalling must be disabled in the INSYS Modem 56k AC/DC 4.2 that a connection is accepted regardless of the status of the application. The status of the hardware data flow control (enabled by default) must also be considered. It answers after the configured number of ring tones and opens a connection. Configuration with AT commands The HSComm enables to establish a connection via the integrated terminal program. Click "Terminal" (page 36, Figure 7: HSComm Modem - Modem, position 3) in the menu bar of HSComm, to open the integrated terminal program. Configuration with AT commands In order to establish a data connection with the INSYS Modem 56k AC/DC 4.2, use the command ATD<number> Replace <number> with the phone number of the remote terminal. In order to explicitly use tone dialling for dialling the number, use the command ATDT<number> 39

Functions INSYS Modem 56k AC/DC 4.2 In order to explicitly use pulse dialling for dialling the number, use the command If the remote terminal accepts the connection, the INSYS Modem 56k AC/DC 4.2 indicates If the remote terminal is busy, the INSYS Modem 56k AC/DC 4.2 indicates If the remote terminal is no modem, the INSYS Modem 56k AC/DC 4.2 indicates after the remote terminal has picked up If the INSYS Modem 56k AC/DC 4.2 does not receive a dial tone after picking up before dialling, it indicates If the INSYS Modem 56k AC/DC 4.2 is connected to a telephone system, it may be possible that no dial tone, but a different acoustical signal is audible after picking up. To configure the INSYS Modem 56k AC/DC 4.2 that it does not wait for a dial tone before dialling, use the following command before dialling ATDP<number> CONNECT BUSY NO CARRIER NO DIALTONE ATX3 In order to change to command mode during a data connection, use the escape sequence 40 No data must be transmitted for 1 second that the INSYS Modem 56k AC/DC 4.2 changes to command mode. In order to change from command mode to normal data transmission again, use the command In order to accept an incoming connection, use the command +++ ATO ATA

INSYS Modem 56k AC/DC 4.2 Functions In order to configure the number of ring tones after which the INSYS Modem 56k AC/DC 4.2 answers and accepts the connection, use the command ATS0=<n> Replace <n> with the number of ring tones. In order to terminate a connection and cause the INSYS Modem 56k AC/DC 4.2 to hang up, use the command ATH 11.2 Select Country-Specific Presets Note Loss of saved settings Changing the country code will reset all stored settings in the INSYS Modem 56k AC/DC 4.2 to factory defaults (except the country code setting). Download (or make notes of) the settings of your INSYS Modem 56k AC/DC 4.2 before you change the country specific preset. The INSYS Modem 56k AC/DC 4.2 holds a range of presets, which allow you to adjust the device to the standards and requirements of the local telephone network. You find a list of countries and the corresponding country codes in the Country Codes section. The default setting is Europe with the country code FD. Configuration with HSComm Choose the preset for the country where you re going to use the INSYS Modem 56k AC/DC 4.2 in the software HSComm on the Modem tab in the panel International Settings (Page 36, Figure 7: HSComm Modem - Modem, Position 14). Configuration with AT commands To choose the preset for the country where the INSYS Modem 56k AC/DC 4.2 is deployed, use the command: AT+GCI=<n> 41

Functions INSYS Modem 56k AC/DC 4.2 11.3 Automatic Baud Rate Detection 11.3.1 Serial Connection The automatic baud rate detection enables a continuous automatic adjustment of all parameters (baud rate, data format) of the serial interface at the INSYS Modem 56k AC/DC 4.2. The device will detect during the operation, which baud rate and which data format is applied to the serial interface. After a restart, the INSYS Modem 56k AC/DC 4.2 will restore the last working interface configuration. With each incoming AT command (according to the character string "AT"), the parameters for the interface of the INSYS Modem 56k AC/DC 4.2 will be checked and adjusted, if necessary. This is the reason why the baud rate can not be stored with the command AT&W, as the INSYS Modem 56k AC/DC 4.2 will immediately adjust its interface to the current parameters of the currently established serial connection. The function is active as default. Configuration with HSComm A configuration using HSComm is not possible, because the automatic baud rate detection will re-adjust the baud rate of the serial interface at the INSYS Modem 56k AC/DC 4.2 immediately after each further "AT". As the software sends several commands, entering an AT command to temporarily change the baud rate in the field "Initialization string" will at best be ineffective. It can also result in errors during the transmission of the settings from the software to the INSYS Modem 56k AC/DC 4.2. Configuration with AT commands To set the baud rates temporarily (until the next "AT"), enter one of the following baud rates for <n>: 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600 or 115200 bps. AT+IPR=<n> This setting can not be stored. The INSYS Modem 56k AC/DC 4.2 must be configured with the baud rate, which is used to operate the application at a later time, as the INSYS Modem 56k AC/DC 4.2 will always use the last known functioning configuration of its interface. 42

INSYS Modem 56k AC/DC 4.2 Functions 11.3.2 Phone Connection The automatic negotiation of the baud rate and the modulation standard enables the INSYS Modem 56k AC/DC 4.2 to negotiate the largest possible connection speed to the remote terminal while the connection is established. The speed depends on the settings and the abilities of the modem at the remote terminal. Via the modulation standard, the connection speed can be set through the phone line. If nothing is defined, the INSYS Modem 56k AC/DC 4.2 will automatically try to determine the optimum connection parameters. The function is active as default. Configuration with HSComm A direct configuration with the HSComm is not intended. The AT command to define a fixed baud rate can be sent to the INSYS Modem 56k AC/DC 4.2 via the entry field "Initialization string" (Page 36, Figure 7: HSComm Modem - Modem, Position 13). Configuration with AT commands To configure the modulation standard and thus the connection speed, use the command: AT+MS=<modulation> Please find the possible parameters for this command in the Chapter "AT Command reference". To display the current settings: For a list of possible parameter of the command, enter: AT+MS? AT+MS=? 11.4 Data Buffer for Serial Data Transmission The INSYS Modem 56k AC/DC 4.2 provides send and receive buffers. These buffers prevent the loss of data, in case the application or the remote terminal can not receive data at this time. The data buffer can be deactivated together with the error correction (bit direct mode). When the buffer is activated, the data flow control should be active to avoid a buffer overflow in the INSYS Modem 56k AC/DC 4.2. If the buffer overflows, the data gets lost. Operation without a buffer and error correction is only useful for special character framings. The function is active as default. Configuration with HSComm Select the type of error correction on the tab Modem in the panel "Phone interface" (Page 36, Figure 7: HSComm Modem - Modem, Position 25). Buffering is active for all options except the option "unbuffered, bit 43

Functions INSYS Modem 56k AC/DC 4.2 direct". To deactivate the buffer (and simultaneously the error correction), select "unbuffered, bit direct". Configuration with AT commands To deactivate the error correction as well as the buffer in the INSYS Modem 56k AC/DC 4.2 for applications with special data format, use the command: To deactivate only the error correction, use the command: AT\N1 AT\N0 11.5 Bit Direct Mode For special applications, the buffering of the INSYS Modem 56k AC/DC 4.2 can be deactivated using the setting "unbuffered, bit direct". All data is forwarded without buffering and further influence of the INSYS Modem 56k AC/DC 4.2. This applies especially to the parity and stop bits. The error correction and the data compression are in this case switched off as well. If the INSYS Modem 56k AC/DC 4.2 is operated in this mode, not all functions will be available. The remote configuration and all functions for which a password is required, will no longer be available. This mode should only be used for special character framings. Configuration with HSComm Select the type of error correction on the tab Modem in the panel "Phone interface" (Page 36, Figure 7: HSComm Modem - Modem, Position 25). Select "unbuffered, bit direct" to switch to bit direct mode. Configuration with AT commands To deactivate the buffer of the INSYS Modem 56k AC/DC 4.2 and to switch on the bit direct mode, use the command: AT\N1 44

INSYS Modem 56k AC/DC 4.2 Functions 11.6 Data Flow Control (Handshake) The data flow control ensures that the data transfer is interrupted as soon as the modem buffer exceeds a certain level. Two data flow control options are available: Via the control lines RTS and CTS, or via the control characters XON/XOFF which are inserted into the data stream. 11.6.1 Hardware data flow control (RTS/CTS) The hardware data flow control works in two directions. When the critical buffer level is exceeded, the modem will set the CTS line to "low" and will thus indicate to the application to interrupt the dataflow. When the buffer is emptied sufficiently for the INSYS Modem 56k AC/DC 4.2 to be able to receive data again, the CTS line is set to "high". Reversely, the application can also indicate to the INSYS Modem 56k AC/DC 4.2 to interrupt the data flow. This is done via the RTS line. If it is set to "low", the modem will interrupt the data flow to the application. The application will set it to "high" to request data from the INSYS Modem 56k AC/DC 4.2. The data flow control with RTS/CTS behavior is active by default. Configuration with HSComm Select the type of data flow control or switch it off completely on the tab Modem in the panel "Handshake" (Page 36, Figure 7: HSComm Modem - Modem, Position 26). Configuration with AT commands To switch the data flow control on and to set the type to RTS/CTS, use: To switch the data flow control off, use: AT&K3 AT&K0 45

Functions INSYS Modem 56k AC/DC 4.2 11.6.2 Software data flow control (XON/XOFF) When the input buffer of the modem exceeds a certain fill state, the modem will insert an XOFF character into the data stream to the application. This character will cause the application to send no more data. It will depend on the according application software if the XON/XOFF data flow control is supported. After the input buffer of the modem is emptied so much that data can be received again, the modem will send an XON character to the application. This character will cause the application to send data to the modem again. Analogously, the application can insert XON/XOFF characters into the data stream to switch the data flow on and off. The XON/XOFF data flow control is only available when the transmitted data do not contain the characters XON or XOFF, which usually appear only in actual ASCII texts (7 bit). When binary data (programs, etc.) are transmitted, or in the XMODEM transmission protocol, for example, occasionally appearing XON or XOFF characters would disturb the operation. Configuration with HSComm Select the type of data flow control or switch it off completely on the tab Modem in the panel "Handshake" (Page 36, Figure 7: HSComm Modem - Modem, Position 26). Configuration with AT commands To switch the data flow control on and to set the type to XON/XOFF, use: To switch the data flow control off, use: AT&K4 AT&K0 46
