APPLICATION
Following is an example program for use with a
CR23X connected to a computer via a COM200
Datalogger Telephone Modem, a COM300
Datalogger Telephone Modem in data mode, or
COM100 Cellular Transceiver. A modification
may be needed to the modem string in the
PC208W Setup screen. If the string contains
an &Q setting, it must be set to &Q0 for 1200
baud (&Q5 for 9600 baud).
