2 * The interactive command entry (editing) function in libcommon
3 * will call mygetchar() for its character input. It is supposed
4 * to be a blocking wait for input, but in some programs other
5 * processing can be done while waiting - for example, check for
6 * keypad presses as well. This is the basic version which waits
7 * for serial input and nothing else.
