6pack can be setup on the AX.25 Packet LAN as a Token ring with one
node being the DAMA master, and all the others slaves. I this is good
for busy channels. If someone wants a real challenge the linux kernel
space driver would cause an instant kernel panic, but this may be ok
now that they have fixed the linux ax.25 kernel space bugs. I have
not tested my new setup with 6pack yet.

Yes, multiple TNCs on a serial port are supported by the BPQKISS EPROM.
Although I'd heard of 6pack I'd never looked closely at it. The 6pack protocol, even if not used for controlling more than one TNC, seems to give the host much better control of channel access, as the channel status (DCD) is passed to the host and PTT timing is controlled by the host. This could improve ax.25 protocol timing and facilitate interlocking ax.25 and other protocols on the same radio.
I think it will be worth me looking into adding a 6pack driver to BPQ and 6pack protocol support to QtSoundModem.
Thanks, Chris for bringing this to my attention.

This can be done with bpqkiss also.. works great,did run 3 tiny-2 this way on one com port.

I uploaded the linux source code for the driver, and (the translated) web pages from the old German flexnet site in case anyone wants to take it on.
I found it in archive.org's wayback machine. I also included the 6pack eprom in the zip file.

I think the coolest thing about 6pack is the way you can daisy chain TNC's via just their RS232's TX and RX's together in series like a token ring network. Doing this lets lets you run multiple TNC's on one rs232 PC port.
