That was a good hint! My nullmodem connector had local crossed RTS/CTS
and DSR/DTR as I use a 20m long 3-wire connection. - I - assumed that would
be enough, as it worked well with AmiTCP.

After some searching in /dev I found some mysterious device ttyA1, which
seemed to be the direct serial device. (why is it named 4A', like seriAl ???)
What is the exact difference between ttyM1 and ttyA1 except the way they
handle the hardware handshake signals ?

A new slattach command started my network, and now its running perfectly !

Thank you very much !
