8. Communicating with the GL61x0
After setting up the GL61x0, communications can be established by directly sending AT commands to
the device using terminal software such as HyperTerminal for MS Windows. The following sub-
sections describe how this is done.
8.1. Communications Testing for the GL61x0
To perform a communications test after the GL61x0 has been setup, do the following:
 Connect the RS-232 link between the external application (DTE) and the GL6100 (DCE).
 Or connect the GL61x0 with the USB interface. The COM Port number could be checked
under the Device Manager. (Refer to section 6.2.1.3 Setup Communications with the GL6110:
USB Connection)
 Configure the RS-232 port of the DTE as follows:
 Bits per second: 115, 200bps
 Data bits: 8
 Parity: None
 Stop bits: 1
 Flow control: hardware
 Using a communication software such as HyperTerminal, enter:
AT
 When communications have been established, the GL6100 will respond with an “OK”, which
is displayed in the HyperTerminal window.
If communications cannot be established with the GL6100, do the following:
 Check the RS-232 connection between the application (DTE) and the GL6100 (DCE).
 Check the configuration of the COM port used on the DTE.
Refer to the table below for other AT commands that can be used after getting the GL61x0 started.
Table 29. Basic AT Commands for the GL61x0
AT Command
Description
AT+CGMI
To check if the serial link is OK. The GL6100 will respond with "WAVECOM
MODEM" when it is OK.
AT+CPIN=xxxx
To enter a PIN code, xxxx (if activated).
AT+CSQ

AT+CREG?
To verify the registration of the GL6100 on the network.
ATD<phone number>
To initiate a voice call.
