/* GetSer() - gets a character from the serial */
/* buffer */
/* */
/* PortInit(port, baud, parity, data, stop) */
/* returns 0 if ok */
/* -1 if port not there, */
/* -2 if invalid parameter */

/* IsCarrier(port) - returns a non-zero if */

/* Xmit(ch) - transmit character ch */

/* SendStr(char *Str) - Sends specified string to */
