Hi!
I have a little problem with FreeBSD and a 33.600bps modem with a 16550A
UART chip .

My modem is an internal 33.6BPS configured as a COM3-IRQ4 and works
correctly with dos and Linux . There is wat Linux says about it ...

Changing jumpers on the card to get COM3-IRQ5/7 is impossible cause
of the conflicts with sb0 (irq5) or lpt0 (irq7) ; Anyway , changing
the jumpers to a com3-irq5 conf works ( detected correctly at boot )
but doesn't works with minicom and other comm programs ( the modem
seems 'delayed' by something and i have to press a key to see the
modem's msgs...)
Wat is the story ....? I spent last week trying to get the right
conf but all works was ininfluent . The only thing i can say is
that linux detects the modem correctly and all works perfectly .
Is a sio.c/isa.c bug ? i hope not ....
please help me ....
