+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.
