serial port communication

[Laumann, Lynn Alan]

   I am currently working on a project involving an Everex Step 386 25 mhz 
(IBM compatible) and a CalComp 95480 model digitizer. I'm having trouble 
 locating the asynchronous communication software required for the Everex
 to recieve information input on the digitizer, and vice versa. I have tried
 DOS interrupt calls, Bios calls and even the MicroSoft C function for serial
 port communication, with no luck.
   
   Any information would be greatly appreciated. Please email me at:
   lal at cs.ucsb.edu. Thanks!
