Update
You may write your own code for the mobile computer to communication with the 8400
GPRS Cradle via the terminal port (I/O pins). Refer to a separate programming guide.
TRANSPARENT MODE
Use AT commands to configure PIN code and GPRS AP name. Then, follow the
programming flow of WLAN Example (802.11b/g) using NetInit(7L) in C or START
TCPIP(7) in BASIC.
MODEM MODE
An example is provided below.
char c;
SetCommType(1,COMM_DOCKING); /*Set COM1 for terminal port (I/O pins)*/
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*/
{
…
}
