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?

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.

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).
