^T6 - Indicate Status of Cellular Phone
The status of the cellular phone connected to the modem is reported in response to the
^T6 command. The status is reported in a single byte formatted as a decimal number. The
individual status signals assigned to the status byte bits are:
bit 0 1 = Cellular phone is receiving an incoming call
bit 1 1 = Cellular phone is in use
bit 2 1 = Cellular phone is locked (cannot be used)
bit 3 1 = There is no service for cellular phone (does not indicate signal
strength)
bit 4 1 = Cellular phone is powered on
bit 5 1 = Cellular driver is initialized
bit 6 0 = Reserved (0)
bit 7 1 = Cellular cable detected
Result Codes (typical):
128 (Cellular cable detected)
OK
Application of ^T6 Status Byte
The information obtained by issuing a AT^T6 can be used to determine if the loading of
the cellular phone driver is necessary by the host software. A download is not necessary
if landline (or no cable) is connected to the modem, in which ^T6 will return a value of 0
(bit 7=0). A download is necessary when a cellular cable is detected (implied cellular
phone is also connected), in which ^T6 will return a value of 128 (bit 7=1). Once a driver
is downloaded to the modem, it will be able to operate in landline or cellular mode based
on detection of a cellular cable.
