I am wondering what the best NETROM parameters for an effecient
netrom link over a 1k2bps link. My current setup is a but clunky
in comparison to a UROnode->BPQ32 link that I have on the same port.
I the link effeciency is decent ~80%, but a straight AX.25 -> AX.25 link
is much better. When I use NETROM->NETROM with the native linux
stack and say BPQ32, cannot tell the difference between that and
a plain vanilla AX.25 link, but with JNOS this process is slow.
Here is the pertenant settings for my autoexec.nos file:

# Place your CALLSIGN and ALIAS (NetROM Nodename) here:

netrom call K6HTN-3

#
# Only enable these if using BPQ AXUDP Internet links if they have
# been uncommented, above. This sets the initial routing 'weight' value.
