It is supposed * to be a blocking wait for input, but in some programs other * processing can be done while waiting - for example, check for * keypad presses as well. This is the basic version which waits * for serial input and nothing else. */ extern int serial_in_poll(); int mygetchar() { register int c; do c = serial_in_poll(); while (c < 0); return c; }
