However, Hartmut may not have the complete story.  One David Jones here
in the UK has distributed a shareware program which he claims provides
the conversion from V22 (1200/1200) to V23 (i.e. 1200/75).  I came
across a copy whilst tidying my disks recently, and could probably post
if prompted (it was less than 2K).  A disclaimer - my modem can generate
split rates internally, so I've never had cause to try it out myself.  

I recall reading a description of the kludge by which this was done, I think
written by David Jones himself in the very early days of the ST.  
It may be in the 'Best of Bix' section which Byte published at one time.
I think David has some connection with the CIX system here in Britain.
