Hi All: I am looking for a serial communications library for the DOS/32 environment. I am maintaining an old DOS lab program (as in, 16-bit real mode!), and it is getting too big to fit in 640K(*). I would like to get it to run in DOS/32, but I need interrupt driven communications to the serial ports. Does anyone have any recommendations? Thank you very much for your time! (*) Yes, I have considered getting it to run under Linux, or Win/32, or... For mostly logistical reasons, this is impractical. DOS it must be.

Four files there start with serial (two are assembly files, so I surmise you'll need to go after a version of MASM in the Net, not exactly a big problem). HTH -- Cesar Rabak GNU/Linux User 52247.

Dear Cesar: Thanks for the pointer. I had trouble finding the files. When I expanded the x32.zip file into \dm, the files ended up in \dm\examples, rather than \dm\samples\dos\x32. I looked in \dm\samples\dos, and the only directory there is "piano". I double checked the CD, and the files are not there. Hmm. Anyway, I did find them, and they do work. They are pretty, ah, minimal, however. They don't allow setting the port parity, data bits, or stop bits at run time (you can change the compile time constant that is jammed into the register, but I need run time initialization). Maybe I'll change the code and send it to Digital Mars... Another reader has offered me some code, so I'll take a look at that first. Thanks!

And yes, if you can, add this functionality and send back to DM so the product gets more useful. -- Cesar Rabak GNU/Linux User 52247. Get counted: http://counter.li.org/

Does anyone have any recommendations?I've writen a small interrupt driven C-module for DOSX that I use in my apps since years. It doesn't need ASM. If you are interested I can mail it to you as source files. Regards, Heinz

Dear Heinz, Thank you very much for your offer! I would greatly appreciate the source code! It would help me keep this program working.
