Yes, one small difference is that 2.0.36 writes tty03 and 2.1.125 writes ttyS03
My device is called /dev/ttyS3 but it doesn't matter. Same interrput values do work okay with 2.0.36. What shall I do to make it work under 2.1.125?
Anyway, I have no setserial command during boot (I've explicitely purged those since they just set the same values, but using /dev/cua*).
Thx Egmont Koblinger
