Interfaces

Documentation Home

Interfaces are how SNOS connects to other applications and other systems.

Interfaces are described using attach commands, and configured using ifconfig commands.

Interface defaults can be set using the ax25, ip and tcp commands.

Attach commands

Ethernet

attach packet iface interrupt mtu
Example:
attach packet et1 0x60 1520

There should be an Ethernet controller attached, so that SNOS can communicate with Windows applications.

A G8BPQ switch using BPQENET.

attach bpqenet iface vector mtu quality

Example:

attach bpqenet ax1 0x60 256 240

COM Ports

COM ports are normally used to attach KISS TNCs to SNOS. They can also be used directly by a simple terminal program in SNOS so that you can set up the TNC and place it in KISS mode.

attach com iface address vector ibufsize obufsize speed [to_iface]
Example: a normal COM1 interface.

attach com com1 0x3f8 4 64 64 9600

KISS TNC on a COM Port

First channel:
attach kiss/xkiss iface com_iface channel mtu qual
Example: a KPC-9612 using standard kiss mode plugged into COM1.

attach kiss ax2 com1 0 256 224
attach kiss ax3 com1 1 256 192
