Hello.

it probably depends on the linker used to create the clipper app, here we use blinker to create a protect mode application
Yes, the prog I now have, also uses
blinker.
Btw, in both dosemu-1.2.1 and 1.3.0
it works only in real mode since the
proper Blinker support was added only
in 1.3.1. Does your prog work in real
or protected mode for you?

In 1.1.3 (which is the dosemu we use)
1.1.3 is too old and buggy. Why are you
still using it? 1.3.0 or 1.3.1 should
be much better.

I had to make the changes I told you, and I
use hog_threshold(0) to have the clipper app to give back all the time it doesn't use.
OK, but not everything is clear.
You said you call usleep() every 50th
call and set $_hogthreshold=(0).
But then, if you set $_hogthreshold=(1)
with an unmodified dosemu, it should
call usleep() on *every* call of int21/ah=2c,
so it must release much more CPU time!
How it happens that it doesn't?
(please see int.c line 1201, where 0x2c
is trapped).
