I'm using a Sportster 56K FLash (not voice), but a few of my settings seem
to be different, for what its worth:

U.S. Robotics Sportster Flash 56000 Settings...
   B0  E1  F1  M1  Q0  V1  X4  Y0
   SPEED=115200  PARITY=N  WORDLEN=8
   DIAL=TONE   OFF LINE
   &A3  &B1  &C1  &D2  &H1  &I0  &K1
   &M4  &N0  &R2  &S0  &T5  &U0  &Y1
   S00=000  S01=000  S02=043  S03=013  S04=010  S05=008  S06=004
   S07=060  S08=002  S09=006  S10=014  S11=072  S12=050  S13=000
   S15=000  S16=000  S18=000  S19=000  S21=010  S22=017  S23=019
   S25=005  S27=001  S28=008  S29=020  S30=000  S31=128  S32=002
   S33=000  S34=000  S35=000  S36=014  S38=000  S39=011  S40=000
   S41=006

If you are getting truncated data back, however, I would suspect a flow
control or maybe an IRQ sharing problem?
