/* The connect command is #if 0 because I hadn't thought of an elegant
way to wait for I/O on two `struct serial *'s simultaneously. Two
solutions came to mind:
1999-07-07 22:19:36 +02:00
1) Fork, and have have one fork handle the to user direction,
and have the other hand the to target direction. This
obviously won't cut it for MSDOS.
1999-07-07 22:19:36 +02:00
2) Use something like select. This assumes that stdin and
the target side can both be waited on via the same
mechanism. This may not be true for DOS, if GDB is
talking to the target via a TCP socket.
