This doesn't make sense. The known problems are all timing related, and 
9600 (I presume you mean V.29 at 9600) is no more or less sensitive to 
timing slips than V.17. Actually, on a poor line V.17 at 9600bps should 
perform considerably better than V.29 at 9600bps. Can you tell me your 
exact setup? There must be something else wrong.
