***************************************************************************

There is a problem with (TYI TYI) hanging in "RDTTY mode" which appears
to be caused by the ^B interrupt.  Also, what is the possiblity of using
TEXTI and staying in (STATUS LINMO) => () mode and having rubout processing?
The problem shown above causes minor disasters in things like STEP which
wants a <sp> to continue stepping and it is frustrating to naive users who
don't know to type <sp><cr> to get it working.
