Hi to every one.

I have a little problem with the speed of a modem used to receive connection from other computer to log in my Linux Madrake 9.0 server.

I have configured the server to accept modem call with mgetty with the option AUTOPPP. And this works fine, but the problem is that the modem works at 33600 even if i told mgetty that the speed was 115200 (the line in inittab is "s1:12345:respawn:/usr/local/sbin/mgetty ttyS0 -D /dev/ttyS0 -s 115200").
When I watch the log file for the mgetty transaction I obtain something odd:

10/15 16:12:54 yS0 WARNING: DSR is off - modem turned off or bad cable?
10/15 16:12:54 yS0 lowering DTR to reset Modem

is this related ? What I have to do ? I'm not so smart with the hayes commands

Thand a lot

all i know to do is put -x 7 in the cammand line to bump up the debug level
and see if you get any usefull info

one interesting point is that the speed setting is the setting for the serial port.
now the moden is compressing the data so by definition what flows between the modem and the connection
is less that what flows between the compuer and the modem through that serial port.

Ok,
By the looks of your problem you are having someone dial into your server, now unless you have a server modem your problem will be that standard modems are 56Kb Down and 33.6 (or 28.8 can't remember which) up or if you have a V.92 modem then it is 56/48.


YOU will not get anywhere near 56Kb Up a standard modem dialling to a standard modem will only get the max speed of the UP transmition rate which is either 33.6 or 48 there abouts. (depends on weather it is V.92 or V.91)


Help this resolves your problem.

Have you managed to get dial in to work from Debian? as I have been trying for a while and can't get the modem to answer I can dial out no problems. I think my problem is due to the lucent agere modem that I have, I have tried the linux drivers for it, I have also tried setting AUTO_PPP and mgetty and compiling the source code for both mgetty and ppp rather then using the packages.
