A windows 3.1 guest... It seems I worked out something to make the named pipes 'happy'... First I launch windows 3.1 alone, start up a terminal session @ 19200 baud, then in a command window type in:

type \\.\pipe\slip1

And I can hit one key in the terminal and it'll pop out the pipe... then launch Xenix, and do a simple...

ls -l > /dev/tty1a

and if all is well it'll appear on the terminal....

close the terminal launch the trumpet, then run this on the xenix box:

slattach /dev/tty1a 192.168.0.1 192.168.0.2 255.255.255.0 19200

then connect my trumpet that is configured as 192.168.0.2 / 255.255.255.0 with a 1006 MTU and... I can telnet!

I installed streams. (reboot)
then the tcpip (reboot)
then the supliment (reboot)
mkdev tcp (reboot)
mkdev slip (install/1 port/reboot)
