12.1 Establishing or Accepting a Data Connection
The INSYS Modem 56k small EU 2.1 can call another modem via the phone line and es-
tablish a data connection. After dialling a phone number, the INSYS Modem 56k small EU
2.1 synchronises with the called modem and opens a data connection with the transmis-
sion 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 small EU 2.1
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 small
EU 2.1 processes the entered characters as AT commands and does not transmit them to
the remote terminal.
The INSYS Modem 56k small EU 2.1 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 small EU 2.1 does
not accept the incoming connection. In this case, DTR signalling must be disabled in the
INSYS Modem 56k small EU 2.1 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 26, Figure 5, position 3) in the menu bar of
HSComm, to open the integrated terminal program.
Configuration with AT commands
In order to establish a data connec-
tion with the INSYS Modem 56k small
EU 2.1, use the command
Replace <number> with the phone
number of the remote terminal.
ATD<number>
In order to explicitly use tone dialling
for dialling the number, use the
command
ATDT<number>
In order to explicitly use
pulse dialling
for dialling the number, use the
command
ATDP<number>
