USRobotics Modem Trouble
 
:) ok my original modem was a winmodem and it sucked, so i went through the junk pile (my closet) and found a USRobotics 56k sportster flash modem!

i'm using REDHAT9..

well on startup kazaam (name??) picks it up and i configured it.. everything was going well.. but i can't seem to dial out on it.. i've dropped into the terminal and fed lines into it such as

(its on ttyS0)

echo "ATA" > ttyS0
it picks up!

echo "ATDT0407021300" > ttyS0
nothing.. it seems all the lights flicker, i don't get anything...

so i tried to go into network config and install and activate it... still nothing happens...

i'm in windows atm and its working fine, can anyone give me any advice on how to fix this? its a pain, to access this forum i must log out of RedHat9 and log into windowsXP

i'm still very new to linux (3days) and still have little idea, pardon my ignorance if its something simple :)

It probably is. The most likely thing I can find is your commands being way to simple.
I sometimes use a PC-Card modem, in order to dial, I have to pass it a string like.. ATDT &F1 &c3 &d &e &g &this&that &speed & protocal... blah blah.. its like a whole paragraph long. You'll need to go find the online manual for your modem, on US robotics website, and figure out a nice long string that tells the modem everything it has to do :)

on it right now! shouldn't redhat know this though? it picks it up as a USRobotics sportster flash... when i get this working, and figure out how to code this stuff, i'm going to fix a heap of stuff :) c/c++ is a favourite of mine

no go... USRobotics just says ATDT no "to dial out"
and theres nothing there saying initalise modem so i'm guessing its standard ATZ thanks anyway CAEDA anyone else got a suggestion?

You didnt quite understand that.
Its not going to be listed under initialse in the manual. You have to read the whole thing. Then, you have to make a custom init string. Which will tell the modem... Turn on.. use v.90 use upstreem speed ???, use downstream speed ???, and so on, for every single feature the modem needs to use. Redhat wont do this by itself.

Here's a list of normal init strings needed for a modem to function.
