Tried & Tested Modem Init Strings

Most of these modem init strings seem to work very well.  If you have a problem that these modem strings don't fix, we are always finding new ways to solve some of these issues.  If you have a modem init $tring that seems to work well please send email and we'll will test and add it to the list.  We have used all these $trings to connect these modems to a Lucent MAX 4048 modem bank, using FLEX chipset with the V.90 firmware installed.  Some ISP's use different technology, so your results may vary.

The only way to get this modem online is to put four commas after the phone number. Yes it sounds strange but it does work.  For some unknown reason the VSC ignores the 56K tone, and spins into a for-next-loop trying to decifer the tone. (1 comma = 1 second pause in operations.)

Tip: You may also want to try one of these generic init strings: 

AT&F 
AT&F1 
AT&F&C1&D2 
AT&F1&C1&D2 
Tip 2: For K56flex modems, try one of these generic init strings: 

AT&F+MS=56 
AT&F+MS=56S202=32 
AT&F1+MS=56 
AT&F1+MS=56S202=32

NOTE for Windows 3.1, WFWG 3.11: Windows 3.x does not support device speeds above 19,200 bps. If you have a 28.8 Kbps or higher modem, you are going to have to edit the win.ini file manually to raise the port speed to a level that will support the modem (for 28.8/33.6 modems, use 57,600; for K56/X2/v.90 modems, use 115,200). You will also need to use a different comm driver, since the standard driver won't support those speeds.

These files will help you set the port speeds:
