You may edit your own code for the mobile computer to communicate with the 3G/GPRS
Cradle via the Cradle-IR interface. Refer to a separate programming guide.
MODEM MODE
An example is provided below.
char c;
SetCommType(1,COMM_IR); /*Set COM1 for IR*/
open_com(1,BAUD_57600|DATA_BIT8|PARITY_NONE|HANDSHAKE_NONE);
…
clear_com(1);
write_com(1,
”
AT\r
”
); /* Send string or char to COM1*/
while (!com_eot(1));
while (1) {
if (read_com(1,(void*)&c) )
/*read COM1 buffer data and save it in the C*/
{
…
}
…
}
…
Note: If you are programming in BASIC language, make sure the default delimiter 0x0d
(CR) is in use; otherwise, call COM_DELIMITER().
