I only find a book for a 33.6 KBd modem, but it looks like the max. 
attempted connection speed is controlled by register S37, with commands 
like:

ATS37=<code>

My code list goes up to 19, the last few being:

  ...
  15 => 26,400
  16 => 26,400
  17 => 28,800
  18 => 31,200
  19 => 33,600

After that you're on your own. Go fishin, I guess - maybe some "name"  
manufacturer posts a more complete set of codes, or take apart a dialing
sequence from [say] Seyon.

HTH.
