[PLUG] modem troubles

hi, i have this pretty straight forward ISA modem, 33.6 and running
off /dev/ttyS3:

orange:~> setserial -a /dev/ttyS3
/dev/ttyS3, Line 3, UART: 16550A, Port: 0x02e8, IRQ: 3
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000
        Flags: spd_normal auto_irq

i am running 2.4.2, serial.o is inserted into the kernel as a module
by kmod, and i use minicom for testing right now.

it's configured to go via /dev/modem, which is a symlink to ttyS3,
115200 8N1 as usual. and on the upswing, it kind of works: i enter
ATZ^M into minicom and it responds with OK.


it takes between 10 and 20 seconds to respond with OK. that's not
normal... and it looks almost like an IRQ conflict to me. but nothing
is reported in the logs.

i don't have a manual for the modem, nor can i find info online as i
don't even know what brand it is. all i know is that it uses the
Rockwel RCV288DST chipset R6628 and that's about it. nevertheless, the
above configuration 0x02e8/irq3 looks absolutely fine for an internal

do you guys have any experience, tips, hints, whatever?

thanks a lot!

all i ask of life is a constant and
exaggerated sense of my own importance.
