I could use a "third eye" on fine tuning the 56k baud packet interface
to Linux. Here's where I am at:

The 56k port is via a PackeTwin interface (serial sync rs-422) that is
connected to the linux kernel as dmascc0. This interface is then sent
into two directions, The first to Tnos using the Net2Kiss feature and
also to ax25-utils inwhich a port in xfbb (7.01f) is linked.

Some tests are as follows:

Telnet from the linux console, using the destination IP Addr, gets a
response from the destination site but nothing shows up on the screen.
Telnet from the Tnos console and I get an immediate connect and
destination prompt.

Connection from a distant source to the ax25-util node, I get a good
connection and handshake. This also includes a successful connection to
the LinFBB bbs (7.01f) via the linux node.  Connection directly to the
xfbb callsign works but I get constant transmit/recieve frames going
back and forth too/from source-destination (kinda like a highspeed
pactor).

Using the CALL application from the linux console works great to the
destination.

Current linux interface mtu is 576 along with the Tnos mtu. ax25-util
mtu is 256 as-well-as the LinFBB settings.  I was just wondering why it
works great from the Tnos and Call applications but not from the Linux
console or LinFBB application?

Last question is regarding the Linux Node.  I have the node set up with
a netrom and netnod ports with the netrom being the dummy switch port
(callsign-10:#alias) and the netnod (callsign-3:alias). I have
configured netrom neighbors using the nrparms commands as well. Along
with this I pointed the linux node across an axip link to another Tnos
machine also running netrom with handset parms.  After a bit of time
these nrparm routes die off which leads me to thing that the linux node
does not hear any broadcasts. I do have the permissions set to '1'
within the nrbroadcast:

145                   5       192     140     1
439                   5       222     140     1
dmascc0         5       222     140     1
dmascc1         5       222     140     0

nrports:
netrom  KC6IKE-10       #SAW    235     Switch Port
netnod  KC6IKE-3        SAW     235     Real Node

rc.local nrparms lines:
# NRPARMS
/usr/sbin/nrparms -node AA6QN-3 + SEE 222 6 axip AA6QN-3
/usr/sbin/nrparms -node WB6DGR + ARESBB 222 6 axip AA6QN-3
/usr/sbin/nrparms -node WB6WLV-10 + OTAY 222 6 dmascc0 WB6WLV-10

I am using node-0.3.0

Thank you in advance, John
