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:

DOS and bios calls bite the big one and I'm sure the Microsoft C functions just interface to one or the other of those. (Knowing Microsoft it probably uses the bios. Microsoft is notorious for bypassing Microsoft DOS but then who can blame them :-) ) The best thing for you to do is get a good book on the serial port hardware and write your own routines. I suggest something that is interupt driven and buffered so that you can keep your throughput up even if you run this program on a slower machine. Even on the Everex Step (Supposedly the fastest machine in it's class) interupt driven ports are good if you use some sort of multi-tasking software such as DesqView or Multi-Link or even better if you decide to run a real OS (Couldn't resist that). -- D'Arcy J.M.
