It is a pity. I have been distributing Flexnet 3.3g to my users without
Internet access, and both the Baycom modem driver as the sound card driver
work very well and most important of all, they accomodate automatically to
the changing traffic. What else is best for packet rookies ? The problem
now is with those users that use fixed parameters software set for
optimistic, low load situations, during peak usage hours. You hear bumper
to bumper, clashing packets....Not only dynamic parameters, but DAMA is
needed as well, because some users do not hear the others and plain run
over them.
TSTHOST users seems to be working well with TFEMU, as well.

That sort of copyright issue is delaying the wider adoption of Flexnet. On
the packet network you find very vocal defenders of Flexnet, but in a
way that does not suit us under Linux. Since we have no 640 K barrier
under Linux, forcibly using a separate computer for Flexnet should not be
an issue.
Once you see Flexnet in action, and actually, I have just seen the dynamic
parameters in action, you realize that it is the sensible way to go. Or
perhaps we will have to wait for other schemes to reinvent the wheel under
other names that do likewise, perhaps half as well because noone outside
of the core developers knows all the tricks involved or is willing others
with the will and the knowledge to arrive at a Linux version do it ?
I have not tried XNET or TNN, but from what I have read, it may be a bit
involved. I used AWZnode for a time, but it seemed to me it uses fully
static port access parameters...maybe I'm wrong.
What is a fact is that parameters must accomodate the load and the amount
of users. If not, it is a waste, and you end either with a truckload of
collisions or something slower than a turtle.
I am using TCPIP mixed with AX.25 on the same channel. It may coexist with
Flexnet, since both back off. But facing plain AX.25 TCPIP sometimes just
backs off too much.
