12 Operation: Using a PC to transmit and receive data
!
Your Personal Computer is directly connected to the SAGEM RT3000 via its RS-
232 port or its USB port. Make sure that you have installed the modem driver of the
SAGEM RT3000 (see, page 39). When you connect your PC to the USB port, then
the RS-232 port is switched off.
!
The SAGEM RT3000 is functioning like a GSM modem. The called party can be a
GSM modem or a fixed network modem.
If the called party's modem is connected to the fixed network, it must support
9600 bps (V.32) / V.42 for the connection into the fixed network. This is necessary
for the communication to the GSM network.
!
To use the GSM modem functions of the SAGEM RT3000 for data communication
you can use any terminal program, e. g. HyperTerminal.
Like an analogue modem the SAGEM RT3000 is controlled by AT commands. You
will find a list of the AT commands on page 62.
!
By default an incoming data call comes in at the Fax/Modem/Phone port of the
SAGEM RT3000, so that a device connected to this port gets the call. If you want to
receive data calls by the PC connected to the SAGEM RT3000, you have to make
the corresponding setting. See Select Port for Data Calls, page 32.
