BPQtoAGW Driver for BPQ32 switch.

BPQtoAGW

This driver gives BPQ32 access to any comms hardware supported by AGW Packet Engines, such as sound card modems. Note that AGWPE acts simply as a KISS TNC, and is not involved in any AX25 level protocol. All timing is done by BPQ32. A PORT entry is required in BPQ32.cfg for each AGW port to be used by BPQ.

IOADDR is the TCP port that AGWPE listens on in HEX (1f41 hex = 8001 decimal). CHANNEL maps to AGWPE port number - A = port 1, B = Port 2, etc. The default TCP port for AGWPE is 8000, but if you are using AGWtoBPQ to allow AGW applications to use BPQ, you will need to change the port number used by AGWPE. This example assumes it has been set to 8001. To set AGWPE's port number right click the AGWPE task tray icon, select Setup Interfaces/Winsock Interface/ Setup TCP 8001 and click OK. The port change takes place immediately.

If you want to run BPQ and AGW on different machines, you also need to add additional configuration statements giving HostName or Address, Port, User, Password

User and Password need be specified only if AGWPE is configured to require them, but I recommend you use them if running over an open network.

Any Ports without a specific config will use 127.0.0.1 and port from BPQ32.cfg IOADDR field

Configuration BPQ32.cfg entries for the BPQtoAGW link.
