I won't ... IBM did! ... and I adapted to their decision ... they seem to
have little experience of 3494 on AIX and a lot on Mainframes. I  haven't
got much of knowledge on OS/2 and the "system" is very busy so I have
little or no space for testing. At which speed you set the port of your
switch ... I don't trust the autonegotiation.
