Why did you do that !?!?!?  You can't lock your DTE to a speed lower than
the modem's highest link rate.  It won't work, as you've already
discovered.  OS/2 is quite happy with 57600, or even 115200 if you prefer. 
Incidentally, now might be a bloody good time to add the following line to
your config.sys:

RUN=MODE COM2:57600,N,8,1,DTR=OFF,RTS=HS,OCTS=ON,TO=ON,XON=OFF,BUFFER=ON

Edit COMn:57600 to suit your own requirements, although 38400 is too low
with compressed files, as this will limit your cps rates to no more than
3840 bps (tried a V.34+ here on Friday, and it was running EXACTLY 4000 cps
on a zip file, 33600 bps connect, no compression active...).  :)

Yes, David Drummond and Poe Lim both have it for freq.

PE> Can I use American code instead?  Both official and unofficial stories.  
PE> Actually, semioffical stories too.

It won't work, as the SDL does a checksum on the country code of the
existing ROM code.  If you try, it just barfs, and won't erase the original
code.

PE> 3. My USR has been set up as follows:
PE> AT&F1
PE> ATS56=0
PE> AT&W
PE> And from then on, ATZ.

Looks fine to me, but don't forget to check the DIP switches beneath the
modem as well.  These should be set to 3, 5 & 8 ON, all others OFF.
