US RObotic external Fax modem on Windows Com4, IRQ 3 at address 2E8
If you compare that to the output of cat /proc/tty/driver/serial you find that your modem is configured for /dev/ttyS3 It matches exactly. OK type the following exactly, remember you must type this exactly, case is vital and don't forget spaces where they are indicated. this means space <space>........ space, but do not type these characters. alternately you can cut and paste each example that follows (but not the ones with <space>). as root: ln<space>-s<space>/dev/ttyS3<space>/dev/modem or better yet cut and paste the following as root: ln -s /dev/ttyS3 /dev/modem now fire up wvdial as a regular user: ie su <regular user name here> wvdial If there are any error messages generated by any of the above commands or if this doesn't work, cut and past all error messages in an email to me. OK hope this works. if not we will fix it. Max On Tuesday 04 June 2002 06:23 pm, Forrest Halford wrote:
Okay guys here is the output on the cat /proc/tty/driver/serial command: Again, thanks for all of the help with the linux newbie,....I will try to return the favor. regards Forrest

Yes com 4 is ttyS3
compare the data US RObotic external Fax modem on Windows Com4, IRQ 3 at address 2E8 4-1 match the IRQ 3 and IO address to the results of the command cat /proc/tty/driver/serial do you find a match listed? write down all the linux com ID # that match the irq 3. ok now as root type ln -s /dev/ttyS<id here> /dev/modem
note there is a space between /dev/ttySx and /dev/modem remember to fire up wvdial after each attempt to test modem
(also you might want to check Kde control center information interupts and find that device on irq 3 is "serial" if so it is your modem)
the format is /dev/ttyS<#> and a space then /dev/modem the format is (must be root) setserial <space> /dev/ttyS<#> always do what insides <> but omit ,<> and its contents thats whats up lets cut to the chase please email me the results of cat /proc/tty/driver/serial and I will tell you what /dev/ttySx to use and then your modem will work. max

OK I realy appreciate the help, but this message keeps coming up
my info is such:
US RObotic external Fax modem on Windows Com4, IRQ 3 at address 2E8 4-1 should be linux ttyS3 yes??
When linux is starting up it says...... interupt 3 ttyS3 is 16550A Whatever that means.....
Now for the results when I ldo what you just mentioned..... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ galt@linux:~> su Password: linux:/home/galt # l-s/dev/ttyS3/dev/modem bash: l-s/dev/ttyS3/dev/modem: No such file or directory linux:/home/galt # setserial/dev/ttyS3 bash: setserial/dev/ttyS3: No such file or directory linux:/home/galt # setserial/dev/ttyS1 bash: setserial/dev/ttyS1: No such file or directory linux:/home/galt # setserial/dev/ttyS2 bash: setserial/dev/ttyS2: No such file or directory linux:/home/galt # setserial/dev/ttyS3 bash: setserial/dev/ttyS3: No such file or directory linux:/home/galt # setserial/dev/ttyS4 bash: setserial/dev/ttyS4: No such file or directory linux:/home/galt # setserial/dev/ttyS5 bash: setserial/dev/ttyS5: No such file or directory linux:/home/galt # setserial/dev/ttyS6 bash: setserial/dev/ttyS6: No such file or directory linux:/home/galt # setserial/dev/ttyS7 bash: setserial/dev/ttyS7: No such file or directory linux:/home/galt # setserial/dev/ttyS8 bash: setserial/dev/ttyS8: No such file or directory linux:/home/galt # setserial/dev/ttyS9 bash: setserial/dev/ttyS9: No such file or directory linux:/home/galt #

it is a lower case L
you need to determine the com port that your modem is assigned to. you can do this by knowing what irq your external modem uses an IRQ interupt request is sort of like an adress that is stored in the bios for each piece of hardware conected to the computer the piece of hardware and the processor use this irq to get each other attention and comunicate. we need to know your modems irq generally speaking two devices should not share the same irq because sometimes this causes a conflict we need to know your modems irq get it from kde control center --- information -- interrupts in the list it should be a device called serial write the irq down or find it in windows like i said or get it from looking at the jumpers in your modem and its manual just determine its irq or check your bios setup program for its irq we need to know your modems irq wvdial or any dialup program needs to know the comport that is assigned to your modem the comport is a combination of your modems irq and an IO address represented by a number with you irq for your modem we can determine your com port for Linux at promt type cat /proc/tty/driver/serial find the device that matches your irq or the one that list a baud rate and write down the number at the start of that line its your /dev/ttyS# replace the # with the number you may have to try this with a couple of them that match the irq then use your /dev/ttyS# in the following l -s /dev/ttyS<com id> /dev/modem fire up wvdial and try if not keep replacing the # with numbers 0 through20 in /dev/ttyS# and retrying wvdial each time until it works max

l -s /dev/ttyS<com id> /dev/modem
Is that supposed to be "l" or ?
Also, I do not understand this part....
then type setserial /dev/ttySx where x is a number 1-9 keep doing this until you find your modems irq and the result says unknown and then use the ln comand but replace the ttySx with the ones that match your irq
Thanks, we are getting closer.... 8-) Forrest

ok heres what we do. if it is a dual boot machine boot into windows right click on my computer select properties look in device manger for your modem and for installed com ports what com port does your modem use in windows subtract 1 from your windoze com port # the result its your linux com id and in Linux do l -s /dev/ttyS<com id> /dev/modem or what IRQ does your modem use in device manger windows? determine your modems IRQ from it or it manual
then type setserial /dev/ttySx where x is a number 1-9 keep doing this until you find your modems irq and the result says unknown and then use the ln comand but replace the ttySx with the ones that match your irq
