Dialup connection 109

That is curious. ALL my systems with PCI modems (real ones; i.e., USR 2610B) come in on ttyS4. And they have been this way for at least two years. And a friend's machine was the same way back when Red Hat Linux 7.3 or 9 (I forget which) was current.

To get a clue where things like that are, examinevar-log-dmesg. What to look for are lines like these that show all your serial devices:

Serial driver version 5.05c (2001-07-08) with MANYPORTS MULTIPORT SHAREIRQ SERIALPCI ISAPNP enabled ttyS0 at 0x03f8 (irq = 4) is a 16550A ttyS1 at 0x02f8 (irq = 3) is a 16550A Redundant entry in serial pcitable. Please send the output of lspci -vv, this message (12b9,1008,12b9,00d3) and the manufacturer and name of serial board or modem board ttyS4 at port 0x4068 (irq = 104) is a 16550A

Then dosbin-lspci -v

and look for the IRQ of your modem. I get:

05:03.0 Serial controller: 3Com Corp, Modem Division 56K FaxModem Model 5610 (rev 01) (prog-if 02 16550) Subsystem: 3Com Corp, Modem Division: Unknown device 00d3 Flags: medium devsel, IRQ 104 I-O ports at 4068 size=8 Capabilities: dc Power Management version 2

This way, you can line up the modem from its IRQ to the correct serial device.
