I've checked the DOS tech ref man, but the information isn't there. > Where should I look for this info ? For this info, I refered to a piece of code on one of the PC-SIG public domain disks. There is a file on one of them called PIBASYNC.PAS (340 something) and it has a complete interrupt driven serial driver for the PC. (I't took 30 min to convert to "C") It supports baud rates to 9600 but you can tweak it to 18.2k baud i've been told. I'm using it (in heavily modified form) to build a BBS system. As far as looking up the info, you might look in the Peter Norton series of books (he's a wimp, but there is sometimes some ok info in the books). Hope this helps.
