Modem won't dial in RH 5.1

I just installed RedHat 5.1 with X, and I entered a modem connection - COM3 (which is what it's listed as in Windows 98), DNS, phone #, login, password.

I can click 'enable' and it is listed as active but nothing happens.  The modem doesn't even click on.. nothing.  If I try to load a page with Netscape it hangs indefinitely.  Any ideas?

trippledouble: well.... winmodems dont work under linux... yes your are having IRQs problems but you have to change the hardware settings.... see your modem card and look for jumpers (irq and com jumpers) if you have those jumpers set it to IRQ3 COM2
if you dont have those jumpers your modem does not work under linux

Can you speak to the modem with minicom from the console (a VC)?  If you say "AT" to it, does it *instantly* reply "OK"?

trippledouble: type:  setserial -a /dev/cuaX   where X is the port where your modem is attached to and send us the information.
Since your modem isnt taken by  linux you are probably having IRQs/com problems
also tell us what kind of modem are you running
Best regards

Ok, in minicom there was no response to typing AT

After typing : setserial -a /dev/cua2
Line 2, UART:unknown, Port: 0x03e8, IRQ:4
baud_base 115200, close_delay: 50, divisor: 0
closing_wait: 3000, closing_wait2 : infinite
Flags: spd_normal skip_test

I did notice cua0 and cua2 were both using IRQ 4, and cua1 and cua3 were both using IRQ 3.  Could this be the problem?  How would I trace possible conflicts?

It's an LT Winmodem, and the only other cards I have in the machine are my video and sound cards.  I don't have anything on any of the serial or parallel ports.

Looks like I'll be switching the modem for one I use at work.  This one has no jumpers and when I tried an external US Robotics it dialed just fine.  Thanks for the info!
