Hello Michael,

I currently run a Baycom USCC>4 card (with 4 modems) and four MFJ1270B
TNC's on the BBS machine. The machine runs xfbb, fpac (for Netrom and Rose
routing) and xastir (with HF, vhf and igate ports.

On another machine I have xastir, Linpac and LinKT. I have dabbled with
Xparm in the past.

On another machine I'm setting up for a remote node I use a Baycom serial
modem and a YAM modem.

I guess I'm fairly well versed in setting up a Linux machine for AR
applications except I've never used the parallel port Baycom.

Have you chosen a distribution yet? I recommend you obtain the Debian KDE
iso image debian40r4a-i386-kde-CD-1.iso available here ...

http://cdimage.debian.org/debian-cd/4.0_r4a/i386/iso-cd/

That will install the KDE desktop. I did have a good play with Kubuntu
(Ubuntu with KDE desktop) but the latest releases of Kubuntu have some
(unpredictable) issues with some AR applications. Kubuntu is based on
Debian. I found Kubuntu had undesireable quirks that vanilla Debian didn't
have, hence my sticking with Debian for the in-service machine (and the
systems I'm building up.

I would recommend that for the sort of AR things you are interested in, you
should compile a kernel. The stock kernel is built with multi-processor
support and this clashes with some AR applications. Compiling the kernel is
quite simple with the tools that are available under Debian based systems.

For your KISS TNC's you will save yourself a lot of anguish if you fit KISS
only EPROMs (assuming you have TNC2 compatible TNC's). The KISS
implementation in the standard EPROM has some very serious timing issues.

If you wish to expedite the exchange of information you might want to email
me vk2tv@exemail.com.au

Cheers ... Ray vk2tv
