A plea.

I'm having trouble initializing the RS-232 port on my ST.  The rsconf call takes 6
parameters:
      baud, flow-control, the four registers on the 68901.

My problem:
      The documentation states that passing a value of -1 for the register contents
will leave them alone.  So that's what I do.  I use the Set RS232 configuration desk
acc. to set the parity, number bits etc.  I'm trying to send a full 8bits out to my
synthesizer, but it appears that only 7 are getting there and back.  

   1) am i wrong in assuming that setting the configuration with the desk acc. will
      configure the port for my program?

   2) can anyone list the various values that should be passed for the control
      register values. (ie. do the status registers need to be cleared. what bits in
      the control registers control what, etc.)

I thank anyone who can shine light on my problem.

If the facts do not conform to the theory, they must be disposed of.
