Need Help driving the 633 with C code

HI-

Im trying to use the 633 serial module in a non-PC application. The eventual target will be running C code but now I am trying to work out the routines on a PC. I have the DOS C Serial routines working and I can communicate with the module so I know the hardware is working.

I was looking thru the Win_test cpp sources for the CRC algorithms but I could not locate them. In those sources I did see that some 'old DOS' code was mentioned. That 'old DOS code' is exactly what I could use -- is that available anywhere? If not could you at least point me to the CRC algorithm?

Also, if there is any code available for driving a DOW RTC that would be very helpful.

Thanks very much
Friendly Regards
Tom.
