Using ttyb in input & output

[SPAHNI Stephane]

I would like to use the ttyb port on a Sun-3 for both input & output.  In
fact, I want to connect it to a PAD (camtec) and to be able to initiate
calls or to receive calls from the camtec. The camtec acts as a DTE. Has
some already do this ? The try I made is to use a crossed cable (2->3,
3->2, 4+5->8, 6+20, 8->4+5), and define a the devices ttyd0 and cua0 as
mentionned in the administrator's manual. IfI disable the logins on ttyd0,
I can correctly go through the pad and call. If I allow both input and
output, a "getty" is started and a loop is created between the camtec and
the sun. This loop last about 20 seconds.... then the Sun crashs !  Any
help will be appreciated.
