 #if 0
+/*
+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.
