Well, by the time I was writing that driver I didn't have a 6pack TNC at all, so I wrote a 6pack TNC emulator that is capable of simulating a single TNC. I still don't have multiple TNCs, unfortunately, so I'm planning on extending that emulator for my work :-) You could try EB6EBU's m6pack which is an application level solution to the problem. I'm undecieded, maybe it's even preferable over a kernel solution. > 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.

Mine seems to be ok as long as the machine survives plugging in the USB device and open()ing the device file. Never really looked into it, blaming the driver for now. > > (For dare devils, attaching a remote 6pack TNC via for example ssh sort > > of works also ;-) > > > > Ahh a subversive TNC to spy on a remote network??? It's a strategy that allows attaching the TNC to any UNIX machine, even without AX.25 support. It's a hack but I was playing with it for a while when I ran out of interfaces. 73 de DL5RB op Ralf -- Loc.
