Hello everybody,
We are looking for a software product available on PC (80286 or 80386)
which makes it possible to:
1. execute a DOS-application within a UNIX environment (any UNIX
environment available on PC will do), and to
2. have interprocess communication between a UNIX-task and the
DOS-task.
All help on this matter will be extremely helpful. Please send replies
by mail to btmcrc@kulcs. Thank you.

As for inter-process communication, I doubt if that specifically exists but here is how I would do it. Use mknod to create a UNIX pipe (or 2, input and output). The DOS program can open this pipe as a file and read and write to it. The UNIX process can do the same and you have your IPC. As I don't have (or want) DOS under UNIX, I may be off base on this and welcome comments or corrections if there are better ways. -- D'Arcy J.M.

Given a 20Mhz 80386 box with 8Mb RAM and 150Mb disk on an ESDI controller, how many users using VP/IX have people seen a box like this support under what kind of loads? > Dan Mocsny Snail: -- -*- Please note the _new_ uucp path, if that is what you use -*- Guy Helmer ...!bigtex!loft386!dsuvax!ghelmer DSU Computing Services ghelmer@dsuvax.uucp, helmer@sdnet.bitnet ETA Systems: one year since Control Data killed the dream
