serial modem not found

tucolino · 09-02-2003, 07:31 AM

Hello everyone. It seems that an external modem is probably the best bet when it comes to modems and linux. I got a Modem Blaster, external (DE5621).

No matter what I do, I cannot get this modem to work.

So far, this is what I have done:

Quote:

- Disabled pnp at the BIOS.
- Disabled pnp in the kernel and recompiled.
- Looked up my serial port IRQ's in the BIOS
ttyS0 port: 3F8H irq: 4
ttyS1 port: 2F8H irq: 3
- Ran:
setserial /dev/ttyS0 uart 16550A port 0x3F8H irq 4
setserial /dev/ttyS1 uart 16550A port 0x2F8H irq 3

when I run:

Quote:

wvdialconf /etc/wvdial.conf

I get:

ttyS1<*1>: ATQ0 V1 E1 --

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?

Please read the FAQ at open.nit.ca/wvdial/

If you still have problems, send mail to wvdial-listlists.nit.ca

Anyone have any suggestions?

By the way, I am connecting this to ttyS1. How do I know this? Well, I have a firecracker serial device, which I used to identify the port I am using. I somehow suspect that I can send data through the serial port, but cannot receive any. The firecracker transmitter works with my serial port. But I don't believe that it sends any data back throught the port. Also, a while ago, I tried to connect my calculator through the serial port and had no luck.

Also,

I enabled these in my kernel:

Quote:

CONFIG_PARPORT_SERIAL=m
CONFIG_SERIAL=m

however, I have the following disabled:

Quote:

# CONFIG_SERIAL_EXTENDED is not set
# CONFIG_SERIAL_NONSTANDARD is not set

So what am I missing here? In case you need to know, my motherboard is ASUS A7V333. Thank you very much in advance for any help. I have been trying to fix this for a week and a half now.

Refuse to give up thought

thanks again,

tuco

I'm a newbie with linux but when I 1st started I had some issues with my modem as well. I'm running Red Hat 8.0 and tried (not knowing you could not) using a Win Modem. I went out and bought me a PCI internal modem and it worked like a charm. My suggestion to you (if you haven't already done so) is to disconnected the modem and erase any related software. Reconnect the modem, reload the driver. Believe it or not, had to do that twice before the PCI Modem worked.

In PPP where you query the modem, I kept switching between the different ports, i.e., tty0, tty1, etc., until I found a match.

If I'm off base, please foregive me.

hmmm... i am starting to have my doubts that either the modem is bad, or there is something wring with my serial port. couple of people already told me that this external modem should work out of the box.

first l'll go test the modem on my friend's machine and then borrow a serial port tester. thanks for your reply. I'll keep you posted.

PS. Yeah, I even borrowed a PCI modem from a friend and got that one working. Serial should be easier, and it's not working somehow.

looks like you tried all kinds of complicated commands and options and etc... did you try to set kppp to use /dev/ttyS1 directly? it is usually this simple to get it going. good luck.

--cheers

btw, congratulations on not giving up. i responded to a post the other day where the guy was like, get this "win"modem running or i go back to windows 98. you can bet i wasn't polite (as he was not, either)

dalek · 09-02-2003, 01:50 PM

Do you have something else that you can plug into the port to test it? I only had to point the modem to the right port in the device tab in kppp and it worked.

Strange. Let us know what is going on.

thank you all very much for your help!!!! I am happy to announce that linux did not fail me (of course not!!! what am i thinking?) I failed linux

it turns out that the transformer for the modem was not working properly. it wasnt giving enough current. just had to replace it. i am so happy!!! i was cracking my head over this... thanks again for all your help.
