Configuring AGWPE Ports

SV2AGW's AGW Packet Engine provides a multiple-TNC interface supporting both physical hardware TNCs and a software "soundmodem" working through the PC's sound card and an associated port used for PTT. Any number of the ports defined on the local AGWPE server can be accessed as YAAC ports.

To add a new AGWPE port, click the Add button on the Configure Ports tab. The port editing dialog will appear. Set the port type to AGWPE.

The other parameters you will need to specify for the port are:

Once you have the settings the way you want them, click OK. Ensure that the TNC is connected to AGWPE before you click OK. At that time, YAAC will begin using AGWPE as a communications proxy.

Other programs for other platforms emulate the functionality of the AGWPE server daemon. These include ldsped (for Linux systems using the kernel AX.25 support), Sivan Toledo 4X6IZ's soundmodem program, DireWolf, and the UZ7HO soundmodem.

If you want to create an AGWPE port on a new installation of YAAC using the -createport option, the port_description is of the format:


where serverhostname is the domain name or numeric IP address of the APRS-IS server instance you wish to connect to, such as or, portNumber is the TCP port number of the APRS-IS server (usually 14580), and passcode is the code number authorizing your callsign to transmit to the APRS-IS backbone. transmitEnabled is either "true" or "false" (without the quotes) depending on whether you want this port able to transmit packets. Any digipeatAlias specified here must also already be specified on the expert-mode configuration dialog's Digipeat tab.
