Configuring AGWPE for TCP/IP Over Radio (TOR)

NOTE: TOR only works on Windows XP and earlier versions.

Note: Before configuring AGWPE for TOR, you must install the SV2AGW virtual adapter in Windows. If you don't, AGWPE will still work, but you will get this message every time you start AGWPE:

To configure AGWPE for TOR, right click on the AGWPE tower icon AGWPE Tower Icon in the Windows Desktop System Tray to bring up the AGWPE menu. Then select TCPIP Over Radio Setup to bring up the Dialup <> AX.25 Setup window.

  • Check Enable TCPIP (Recommended Method) - remember that if the TOR adapter has not been successfully installed, you will get an error message when you close this window. (The Enable DIALUP method is for Windows 95 and is not discussed on this website; it emulates a modem in Win95).
  • Setup Routes: Only used if you want exchange information with other TOR stations using a radioport different from the default radio port (see below). Even so, it would be better to use the Windows ARP table to specify a different radio port for a different callsign.
  • Registration: If you have paid for a number, enter it here (the number ties to your callsign). As the screen says, you don't need a number for normal AGWPE use and you don't need a number to run TOR for less than 45 minutes at a time. See obtaining a registration number.
  • Radio: Use the drop down list to select the AGWPE port you wish to use for TOR. To avoid possible problems, do not select "use all ports". If you do, you may get a message similar to this: THE SYSTEM DETECTED A CONFLICT AT ADDRESS IP WITH THE SYSTEM THAT HAS THE HARDWARE ADDRESS 98:BB:BB:BB:BB:BB.

  • Calls and IP Address: Enter the callsign you will use for TOR. enter your callsign; add a SSID number if you wish, e.g. SV2AGW-4. The other fields you see to the right of this entry field will be grayed out for TOR (they appear only if you use the Windows 95 DIALUP method.)
  • VIA Path: Enter the callsign of any station/digipeater that may be needed to relay your packets. If more than one is needed, use a comma to separate the callsigns.
  • PacLen (on the right):  Enter the maximum length of the packets. AGWPE will break TCP/IP sentences larger than PacLen into additional packets into desired Paclen. Suggested values are 300 for 1200 baud and 576 for 9600 baud. (PacLen equates to MTU or MSS values in a wired network, for those of you familiar with these terms.) If your signal path is good and there is little traffic, you can try increasing the PacLen. Alternatively, decrease PacLen if your path or traffic is creating difficulties (slow downs). (Note: Windows may ignore your settings and pick its own.)
  • Pass All IP Traffic to MS TCPIP Stack: generally this should be left unchecked. If you check it, AGWPE will forward all received TCP/IP packets to Windows, including supervisory packets and packets not addressed to you. This is usually not necessary and may slow down your connection. You should only enable it if you understand the implications and have a good reason to use it, e.g. you are routing / digitpeating packets.
  • Allow Broadcast messages: Generally you will leave this unchecked. Broadcast messages are network management TCP/IP packets that Windows "broadcasts" over a network. They will result in very long packet transmissions. These are not necessary for TCP/IP Over Radio, unless you intend to allow others to access a shared folder on your hard drive.
  • Help:...  was not working in ver. 2003.308

You must close and restart AGWPE for any changes you make to take effect.
