PROGRAMMING YOUR MOBILE COMPUTER
You may write your own code for the mobile computer to communication with the 8000
GPRS Cradle via the Cradle-IR interface.
4.1 PROGRAMMING IN C LANGUAGE
An example is provided below. Refer to CipherLab C Programming Guide for details.
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().
