UZ7HO Sound Card Modem Driver for BPQ32 switch.

UZ7HO Sound Card Modem Driver

This driver allows BPQ32 to use the UZ7HO Sound Card Modem in Session mode, where the Level 2 processing is done by the soundmodem. The Modem interface is compatible with AGWPE, so if you want the BPQ32 switch to perform the L2 functions, you can use the BPQtoAGW driver. From Version 0.35b, the SoundModem supports 2 channel operation.

For the driver to function correctly, you need to use at least version 0.35b of the Soundmodem. The Modem can be downloaded from here

The driver configuration is specified in the bpq32.cfg file

MYCALL is set to the PORT config PORTCALL if specified, otherwise to NODECALL. The driver will also accept connects to any of your APPLCALLs, and route the connection to the appropriate Application.

Configuration.

The driver is defined to BPQ32 as an External port, and needs driver-specific configuration.

Specify CHANNEL=A or CHANNEL=B

PACLEN defaults to 64. You may wish to tune this.

The first line defines the IP address and Port of the UZ7HO TNC, and an optional PATH to the Soundmodem.exe file. If PATH is omitted, bpq32 won't start the SoundModem, and you will have to run the Soundmodem before starting bpq32.

For example

ADDR 127.0.0.1 8000 PATH C:\Program Files\bpq32\SoundModem.exe

Note you can run more than one copy of the SoundModem, but each will need it's own Soundcard, TCP Port and folder. So for a second Modem you could have:

ADDR 127.0.0.1 8001 PATH C:\Program Files\bpq32\SM2\SoundModem.exe


Other possible configuraton parameters are:

MAXSESSIONS
Sets the number of simultaneous connects allowed.

UPDATEMAP
The modem logs connects to the Nodemap if you have specified a LOCATOR in your BPQ32.cfg. If you specify UPDATEMAP, stations heard will also be sent to the map.

BEACONAFTERSESSION
Send Beacon after each session
