what kind of modem are we talking about?
sounds like there might be a irq conflict then as well, or your modem wants to try using another com port. is it a hardware modem, if it is you can manually adjust the irq/com jumpers on the board.
have you tried using another irq to test and see if it works, i have mine on irq 9 and on ttyS2.

modem is aztech 56k internal MSP 3880SP-U
based on rockwell chipset

modem works fine in windows 98
in device manager...it shows irq 4 and 03e8

i cannot manuuallly adjust jumpers on the board..hey man im sure there is no prob here as modem works fine in win98se

at first the dialup package in gnome showed modem busy

i entered some setserial commands
and now it says

cannot open /dev/ttyS2...I/O error

can you tell me wherein the prob lies
