AT commands

Tried IBM.com and find drivers and there are no commands for slowering speed or something like that.
Is there a standard command or every modem has its own command set?

Most of them use an extended version originally developed for the Has MODEM. Developed. Most MODEM manuals list them towards the back of the manual. IBM didn’t have the manual? Why do you want to lower the speed? A 56K MODEM usually does that automatically. The maximum speed can usually be adjusted in Windows, if that is what you are using. Larry

IBM has the manual but it doesn`t say anything about set of AT commands. Only one command is mentioned in manual and that is ATS109=2 command for locking V.90 protocol.
Why do I want to slower speed? I live in Yugoslavia and we still have analog centrals (also digital) but in Belgrade there are a few analog. Connection with 56k modems is terrible. I have 33.6 Rockwell and connection is very good. But with 56k is connection drops every 2-3 minutes (depends on time of a day). Because of that I want to slower speed to 33.6 to have a good connection.

OK thanks for that, but I discovered another problem with another modem: OLITEC SELF MEMORY 33600 PNP .It wont dial (no dial tone) even if I uncheck wait for dial tone and put command switch ATX3.
One question that don`t belongs here: how do you manage to answer all of the questions on your web site?

Check to be sure the phone cable is plugged in the correct jack on the MODEM. Go into the Control Panel, MODEMs, Diagnostics, Select the MODEM, More info…

I know a lot of the answers or where to find them. Larry

Modem works fine, cable is OK, but as I said earlier our telephone central is analog and won`t produce dial tone (in that case we put atx3). This modem won`t work with atx3 either! Every modem does?!

It may defective and is not picking up the line/hook, and common problem over here. Larry

It goes off hook and I hear sound signal, on modem speaker, from telephone central but even if I tell the modem not to use dial tone it reports that there`s no dial tone. So everything is ok, the cable from modem to telephone linem, modem is ok, atx3 is send to modem but it doesn`s respond to that command. It says after typing it OK but nothing.
It search for dial tone. (our tel.central is not like yours so we use atx3 command to tell the modem not to use dial tone)
