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*/
{
…
}
