Very Computer

I have a modem on COM4 under Dos/Windows and it works.
But under Linux, I can't make it work... Please help me...
I've read some HOW-TO's (modem, serial and ppp) to resolve my problem, I've
tried setserial, configure inittab etc. but it does'nt work, who can help
me?

Who has already configure a intern modem on COM4 under linux ?
Who can tell me exactly what to do ?

Thanks you... bye!

Have a look at
http://www.math.sunysb.edu/~comech/tools/StonyBrookPPP.html
and read the diagnostics and jump-start sections.
It is a short hands-on manual and I hope it will help.
Cheers,
Andrew

No post is totally useless,

"IT CAN ALWAYS BE USED AS A BAD EXAMPLE!"

Main problem what kind of modem, ISA I hope or external, what manufacturer and
part number and what functionality.
This would be a minimum start to a good post.
I'm surprised anyone tried to help at all!

So, I have a PCTel Inc. modem (intern) on COM4 (under Win95) :

                           COM4        : port adress : 2e8
                                                 irq                : 3

Under Linux, I have configured my /etc/inittab file, I added this:
s4:12345:respawn:/sbin/getty ttyS3 38400 vt100
And in /etc/gettydefs, I added :

38400

This seems to be correct for me... I use ttyS3 (=COM4), 38400 bauds (speed
of my modem).
I boot linux, I login under root, and I type :
setserial -a /dev/ttyS3 and I see that the irq is correct (3), the adress
too (2e8) but the UART is unknow, so I type :
setserial -b /dev/ttyS3 UART 16550A (my UART under Windows)

I think I don't forget any step... but it still not work...
Every five minuts, I can read on the screen :
INIT : Id "s4" respawning too fast : disabled for 5 minutes

What is the signification of this ? If setserial -a /dev/ttyS3 give me the
good irq, the good port adress etc., why doesn't the modem work ?
This isn't a P'n'P modem because I can change irq and port adress under
Windows...

Thank you.

I read your followup message too, and I think you have a softmodem.  Reason
being, you say win9x reports it is a 16550 UART, and you can change the
resources from within windows, but you can't even ID the uart in linux.

HuH?  That kinda makes it PnP doesn't it?  When I plug a hardwired piece of
hardware into a win box, and dare win95 to move it, I get a response that that
option isn't available under windows, but when I do it to a PnP device, it
happily changes it to whatever I tell it to?

check here with the FCC ID#s of your modem to be a bit more certain:

Allen, your followups seem to be messed up .

Reasonable assumption.

Uh. I wouldn't recommend using the standard "getty" for a modem line
anymore. Use mgetty instead.

"setserial"  doesn't actually do anything to the device itself.
You're basically using a program that tells the Linux kernel about
the device's settings (it is sort of an ugly hack). , but if you
are telling it incorrect things, then the results are unpredictable.

The "respawning too fast"  error means that the getty program
couldn't be started successfully, therefor the process respawned
and respawned and respawned...

This makes it either a PNP modem (try using the isapnptools first)
or a winmodem. If it is a winmodem, you're stuck.

No. Definitely not that way.

Please cut down your .sig , Allen.

        How about let's start from the Win95 control panel, since, as you say,
the modem works under windows?  BTW, does your mouse cursor momentarily freeze
when you try connecting under windows?  In your control panel/system
properties/device manager, do you see anything that says "HCF..  or "HCD... And
the real kicker,  under COM ports, do you not see an actual COM port listed for
this COM 4???

If any of these questions are yes (symptoms suggest that they all are), then
that modem will stay with windows, for that is the only OS that it will (ever?)
work under.  Good luck, but it doesn't look real good from here...
