Hi guys,

I don't see any serial port on the wireless G router, WRT54G or GL/GS, and
have checked the versions on Linksys web site, can someone show me where
that port is?

The WRT54G(S) has two serial ports, only a rs232 level shifter is required

OpenWrt (www.openwrt.org) is a Linux distribution especially for this
embedded wireless routers,
see http://toh.openwrt.org/ for a list of supported devices. Be careful,
newer WRT54G(S)-versions
are not supported by OpenWrt, they have to less flash memory.

I would recommend the ASUS WL500g Premium wireless router, nearly the same
platform, but in addition
two usb (2.0) ports, 8 MB flash memory and 32 MB main memory. (about 65 EUR
here in Germany)

As far, as I know, some people are running DIGI_NED on it, but there is an
additional option available.

Since mid of 2006 we (small ham radio group in Germany) are developing an
aprs software called APRS4R,
primary designed to run on embedded devices to reduce power consumption. The
software is written in Ruby,
so the software would also run on each platform with a ruby interpreter
(Linux tested, Windows/OSX untested).

Current release (0.9.9) is the release candidate for the first public

Main features:

- KISS/APRS-IS support
- NEWn-n compliance digipeater (with intelligent path reduction)
- IS-to-RF messaging

- wx support for WMR 928 NX (more stations are on the todo list)
- web interface

If you want more information, please visit http://www.aprs4r.org

I hope, it was okay to make some promotion. The core software is running
stable (mostly ;-)
and we hope to publish the first public release this year.

Kind regards
