I am trying to write a program that talks to an RS232 device that needs
600 baud, 8 bit, 1 stop bit communications with all 8 bits used to 
communicate (i.e., "strip bit" must be OFF).

If I use the control panel to set to 600 baud, 8 bit, 1 stop bit, strip-bit
off, all goes well. But I want to call Rsconf to set this up directly so
the user won't need to do it by hand.

I found parameters for everything except the "strip-bit" control. Is that
handled somewhere else? If so, what do I need to do?

I tried to trace what the control panel does using a machine language
monitor. Besides the Rsconf call, it seems to write directly to RS232 control
registers, but that seemed to be just redundant setting of the same things as
Rsconf is supposed to set... I certainly could have missed something: tracing
machine language execution is nightmarish.

Any suggestions for the missing RS232 calls supported by the control panel
but not present in Rsconf? (Besides "strip-bit", there is also duplex, etc.)

Thanks,
