/*
 * The interactive command entry (editing) function in libcommon
 * will call mygetchar() for its character input.  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.
