Powering up the GC 75 modem and entering PIN code using AT
commands
If Ericsson Phone Modem Manager can not be used as described above it is possible to power
up the telephone and enter the PIN code using AT commands.
1.
This can be done either using Windows 95
®
HyperTerminal or any other terminal program
that communicates directly with the COM port.
∗
AT+CFUN=1 Turns the power to the telephone ON.
∗
AT+CFUN=0 Turns the power to the telephone OFF.
∗
AT+CPIN=”XXXX” Enters the PIN code.
For more information regarding how this is done, please refer to the GC 75 Reference
Manual on the CD. A normal response to the “+CFUN” command is OK, or if anything goes
wrong ERROR, however the “+CPIN” command is more complex and you may need to
request status from the GC 75 modem to determine PIN status. This is done using the
“AT+CPIN?” command.
In addition, most operators allow disabling of the PIN code which may simplify the usage of
the GC 75 modem in this environment.
2.
Modify the init string of the fax or data program you are using.
