LT winmodem redhat 9

Hi everyone,

I am sorry to post about something that has obviously had so much written about it already, but alas I am still unable to get my modem to work with linux.

I have a ISA LT winmodem.

I have redhat 9 with kernal 2.4.20-8

I have used the rpm ltmodem-kv-2.4.20_8-8.26a9-1.i686

I have used ISAPNP to assign IRQ's etc... and I have no conflicts.

I have set up wvdialconf and can get wvdial to see my modem and attempt to send commands.

I have used kppp (it's terminal program section) to send a variety of AT commands and can get replies.

I have installed the noise.tar.gz fix to try and get some sounds from my modem.

BUT still I can not actually get it to dial!!! If I use ATXn commands I am supposed to be able to dial blind without waiting for a dial tone - but when I do this it says NO Carrier... If I ask it to wait for a dial tone it says No Dialtone.

This modem works with windoze... where unfortunately I am writing this post from.

I have turned off PNP support within my bios setup but it still doesn't work.

There is something not quite right.. I know my linux box sees the modem (Hardware Browser sees and id's it) plus I have installed all the modules (lt_modem and lt_serial) and assigned io's irq's etc...

What else can I do to get this thing to work?

If you have any suggestions I would love to hear them. Thanks

it should be assigned to /dev/ttyS04. It should work if the chipset matches yours. The IRQ is 5 btw. It's emulated. I haven't seen an isa winmodem before.. you must have dug deep for that one. Most winmodes modems are pci. Most hardware modems are isa. But that's niether here nor there.

I've been having the same trouble with my ISA windmodem (lucent apollo family luna56) it keeps giving me no dialtone no matter what configuration I use. Although I,m using mandrake 9.1 and compiled my own modules from lt_modem 8.29a9.

Have you had any luck since this post, if so would you post a reply on how you did it.

Thanks John

I never had any luck with the winmodem. I thought about continuing with the search but I gave an external serial modem I borrowed a shot and it worked the very first time using wvdial.

I did read recently about new developments in linux that will support more winmodems, but I haven't really given it much more thought.

If you do have any luck with getting yours to work I'd love to hear about it - I guess one day I should return the external modem I have to the friend I borrowed it from.

Good luck

I finialy got this modem to work in linux, I'm actually writing this from Linux.I listed the steps I used below, not sure why it works but it does(pretty stable).

Thanks for your reply

isapnp /etc/isapnp.conf
#edited/uncommented isapnp.conf to use irq 3 02f8, found in windose, only, i also edited
#isapnp.gone by commenting the same parameters, not sure if this
#actually did anything but i don't want to mess with it since its working
modprobe lt_modem Forced=3,0x0100,0x02f8,0
#The forced parametrs I used were directly from windows device manager
modprobe lt_serial
#found the below in modem docs pack under readme.modules replaced
#with my proper settings
setserial /dev/modem irq 3 autoconfig
setserial /dev/modem spd_vhi
stty -echo < /dev/modem
