Alrighty, heres the deal, either my computer is stupid or I am. I am having trouble setting up my modem, I have a RedHat 7.0 system setup, triple boot. I can get linux up and running and I know my modem works (sorry but I'm on windows now). It is setup on COM3, IRQ 10 (its a zoltix smart spirit modem). I checked all of my linux settings that I know how to check that seemed important, IRQ's and interrupts. I checked my ports and for the serial ports I got:
02f8-02ff Serial (auto)
03f8-03ff Serial (auto)

For the interupts I got:

0 timer
1 keyboard
2 cascade
8 rtc
9 usb-uhci, usb-uhci
12 PS/2 Mouse
13 fpu
14 ide0
15 ide1

I tried setting up with setserial /dev/ttyS2 but that proved fruitless. Any help you guys out there can give me would be more then appreciated.
     Thanks in advance,

I used to use setserial in Mandrake but something advanced in ppp or the kernel or setserial so that I don't have to do that anymore. All I have to do is link the modem to the ttyS device. In your case, I would do:

# ln -s /dev/ttyS2 /dev/modem

and use kppp to set up my dial-up account.

You might need to change permissions on the modem and ttyS2 depending on what group or user wants to use it.

Don't know if that is what is happening in Red Hat but thought I'd throw that out there.

Good luck.

I tried this exactly as you stated a few times and couldn't get it to work, I'm wondering if I might need some drivers for my modem or something like that. I'm not quite that familiar with Linux yet, but this having been my third install that worked for a while I am getting the hang of it and I know that this modem (or a fairly similar variant of it) works under linux because I was refered to it by the ever famous Micheal Holve. Any more help you can give me would be greatly appreciated (as a side note: kppp seems to be better then the default red hat gnome dialer). Thanks for the quick replies too. They help out a lot instead of waiting days for a response.

Sorry, that's about all I know. Try looking here and here.

Good luck.

you can try setting the irq as well in the setserial command:

What trickykid says reminds me that the setserial command I was using for my Actiontec pci modem had a few more elements. I'll post how I went about it in case you still need another option.

First, do # cat /proc/pci

<snip>
Bus 0, device 11, function 0:
Communication controller: Lucent Microelectronics Venus Modem (V90, 56KFlex) (rev 0).
IRQ 10.
Master Capable. No bursts. Min Gnt=252.Max Lat=14.
Non-prefetchable 32 bit memory at 0xdd800000 [0xdd8000ff].
I/O at 0x9400 [0x94ff].
I/O at 0x9000 [0x90ff].
I/O at 0x8800 [0x8807].
<snip>

I take the first I/O and the irq and my ttyS and do:

# setserial /dev/ttyS4 uart 16550A port 0x9400 irq 10

You would need to take the values from your setup and insert them. According to the ppp howto linked in my earlier post, you could find out the uart info with # setserial /dev/ttyS2

Good luck.
