Basic Modem Operation
The initialization string sent to the Trumpcard for cellular connections may
not result in the optimum connection when used for landline connections.
If possible, set the communications software to send the desired
initialization string based on the type of connection being used.
Refer to the section Receiving an Incoming Call for details on how to
command the Modem to receive incoming calls.
Cellular Call Status
The Trumpcard provides a method of determining if the cable connection
to the cellular phone is operational. The AT^T6 command is used for this
purpose and returns a decimal number representing the current status.
The bit map for the status byte is:
Bit # Description
0 Cellular phone is receiving an incoming call
1 Cellular phone is in use
2 Cellular phone is locked
3 There is no service for cellular phone
4 Cellular phone is powered on
5 Cellular driver is initialized
6 –
7 Cellular cable detected
The bit map values have to be converted from binary to decimal. The most
common values are:
160 Cellular cable is detected and driver is initialized.
176 Cellular cable detected, driver is initialized and phone is
powered on. (This state is required to place a call.)
178 Cellular cable detected, driver is initialized, phone is powered
on and cellular phone in use.
