I believe Intel sells a real-time operating system (iRMX?) which has the
capability of running DOS applications. I could be wrong, but contacting
Intel and asking them might get you the kind of information you need.
As to limitations inherent to DOS itself, there are no guarantees on how
long any particular system call will take. However, seeing that DOS
isn't "a real operating system" {grin}, and doesn't take care of
scheduling, none of the real-time issues for scheduling even come into
play when talking about DOS.
