Ralf,
What is lacking that would allow 6pack TNC's to be daisy chained?
By doing so we would be able to use a single serial port to support
multiple TNC's I have the documentation on how to wire the hardware
and that is no big deal.

I have USB running on a laptop, it works well most of the time but
at times when the machine boots one or other ports generates the
"trying to synch tnc" message. The serial port always works. 

I think that at times the USB part is slow to get totally initialized so
I have gone in and added sleeps to slow things down a bit at init.

Ahh a subversive TNC to spy on a remote network???
