Question Another modem question


Hi ppl, Im new to linux so I may be asking some stupid questions here. Im running WinXP/MDK 10.0 dual boot and am having a helluva time getting my

modem (it's not a winmodem) to work on MDK. I've tried the manufacturers special install instructions (their commands didn't work,due to me no doubt

doing something wrong), the new connection wizard from the control panel, kppp setup and nothing's worked. When I query the modem, it tells me its busy.

This is the same modem im using for my XP partition, (busy signal because of that?). XP says my modem's on COM 4, so I set everything in MDK to COM 4.

These are the instructions from the modem manufacturer:

type:


cat /proc/pci

I did that, here are the results:


cat /proc/pci

Next was to take note of the modems IRQ and fisrt I/O range for the serial port and type in:

setserial /dev/ttyS3 uart 16550A port 0xdc00 irq 10
(ttyS3 being COM 4)

I entered this and got a bad command message, several times, making sure I was paying attention to spaces.

The # ./Makedev ttyS3 command wouldnt work either.

Any suggestions would be greatly appreciated. My modem is a ZOOM modem (PCI, controller based, internal, if this matters).

For that command you need to be in /dev/ directory, Or # /dev/Makedev ttyS3
If that dont work this will do the same:

mknod -m $MODE ttyS3 c 4 67 ; chgrp $GROUP ttyS3

Copy + paste if you can! You more than likely already have but nothing will happen if you make it again.

For that first command you need to have the ttyS3 device.
All these commands need to be done as root; you probably already knew that though!

Thanks for your reply Zero, I didn't have any luck with any of those commands either. Im sure im missing something simple but it hasn't smacked me in the head yet.

here's the results I got:

[root@localhost tim]# mknod -m $MODE ttyS3 c 4 67 ; chgrp $GROUP ttyS3
mknod: invalid mode
chgrp: too few arguments
Try `chgrp --help' for more information.
[root@localhost tim]# /dev/Makedev ttyS3
bash: /dev/Makedev: No such file or directory
[root@localhost tim]# cd /dev
[root@localhost dev]# /Makedev ttyS3
bash: /Makedev: No such file or directory
[root@localhost dev]# /dev/Makedev ttyS3
bash: /dev/Makedev: No such file or directory
[root@localhost dev]# cd /
[root@localhost /]# /sbin/ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host

RX bytes:9423 (9.2 Kb) TX bytes:9423 (9.2 Kb)
[root@localhost /]# exit

I did manage to get the ifconfig info this time

Still cant kill that busy signal :S

Maybe I am just to lazy to continue to try to configure my internal modem but I switched to an external serial modem and have had no problems. A used on on EBay isn't too expensive.

mknod -m 660 ttyS3 c 4 67 ; chgrp dialout ttyS3


Whoops! Forgot to subsitute the variables in. The above is the correct command.
That one will definatley work unless its already there in which case you will get a mknod ttyS3 file exists error.
After it is create then do the following (copied from what you put above)


setserial /dev/ttyS3 uart 16550A port 0xdc00 irq 10

No luck with that one either

mknod -m 660 ttyS3 c 4 67 ; chgrp dialout ttyS3
chgrp: invalid group name `dialout'

Ive been messing around with so much stuff on here it's hard to tell what I got screwed up, (can't make an omelette if you don't break a few eggs I guess). So I decided to start from scratch and reinstalled the o.s.
I havent done any modem or internet configuring yet so I'm going to save the info you gave me here and do a lot more research before I try it again, hopefully I can resist the urge to experiment again too :S. I did figure out that setserial doesn't install with the system, you have to install it afterwards. After I installed it, setserial started working, but everything else was pretty much screwed yet.


That ext modem idea sounds tempting alb, but as much hair as I pulled out so far trying to configure this, there's no way I'm can give up on it now.

Thanks again for your help Zero, if you have any advice for configuring from a fresh start, thats where I'm at now and I'm wide open for any input.

Dont just stop and reformat/reinstall. Thats what you would do with windows, not linux.
I would suggest you go forward with it. Getting it to work, going through all these errors and working them out is how you learn. Then next time you go to reinstall you will know how to install it.

You need to create a group called dialout or use another group already on the system.
I dont use mandrake so I cant tell you what groups are there by default.
I really dont like mandrake. Ive kinda got stuck with slackware, and now lfs.
Anyway to create a new group do:
groupadd dialout

Then that command will work. Third time I said that...

I wanted to post this sooner but I didn't get chance till just now. I figured out the prob and modems working fine since about 3 am my time. When I installed this new modem, I didn't take the old one out. When I started having the connect problems, I removed the old one, but didn't move the new one to its slot. Anyway, I installed it the orig pci slot and started up and ran cat /proc/pci, and this time It showed my irq as 11, so I ran setserial again with irq 11 this time and it dialed right up. I'm posting this message from Mozilla instead of Explorer I'm relieved to say.
