5.3 GSM Data Connection (CSD Call)
CSD is the simple modem-like data connection in the GSM network, without using
the GPRS/EDGE service. Remote terminals for the connection can be analogue
modems, ISDN adapter, or GSM devices.
With the help of HSComm GPRS/EDGE, the INSYS GPRS/EDGE 5.0 serial can auto-
matically accept the CSD call. Click on the tab “GSM/GPRS”.
5.3.1 Connection Setup
Dial the number to which a connection is to
be set up (always with area code, except for
special provider numbers).
ATD<phone number>
After the call was accepted; the transfer of
data can begin (e.g. connection with 9600
bps). The successfully established connec-
tion is indicated by the control signal DCD
and the message
CONNECT
.
Connect 9600/RLP
Note
For an active TCP Listen mode, no outgoing CSD connection can be
established.
5.3.2 Incoming Connections
The connection acceptance takes place either automatically, or after a set number
of ring signals, or manually with
ATA
.
To accept a call manually with
ATA
, "0" must be set for "Ring tones until going off-
hook".
The transmission rate is set for outgoing connections from the device.
For incoming connections to the device, the transmission rate is set automatically
depending on the calling remote terminal.
Alternatively, the settings can be entered or modified using the terminal pro-
gram.
