-The connect command is #if 0 because I hadn't thought of an elegant
-way to wait for I/O on two serial_t's simultaneously.  Two solutions
-came to mind:
-
-	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.
-
-	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.
