Some things to document regarding AG
------------------------------------

1. When using MCSI (and Int14 and the Redirector Card), it is not possible
   to get the status of the modem signals CTS and DSR. We will always
   return them as present (1).

   CTS cannot be returned because we program the CTS input pin to
   be directed to the SCC2 for flow control purposes. Once this is done,
   it is not possible to read the state of the CTS pin.

   We currently have no means of reading the DSR input pin state. So
   we cannot return DSR state.
2. If AsyncGateway will be running in a box and a specific WAN has DTR
   dialling enabled, then you should make sure that the modem is
   programmed for a preset baud rate on its RS-232 port.
3. If you find MCSI connections terminating due to retry failures or
   timeouts, increase the timeout for retries.   
4. The way ports are alloted.
5. Direct connect cable for AG use should have TX-RX crossed and RTS-CTS
   crossed and the GND line. Nothing else is required. The box will not
   transmit anything as long as CTS is not asserted irrespective of flow
   control.
6. IPX routing should be enabled for AG to work
