Alex,

even with this patch applied I can print to my serial printer with a

dir > com1:

but not from my clipper (protect mode, telepathy as comx: access library) app...

To be more precise I can print very short strings, that is

tp_open(1...)  // open com port 1
tp_send(1, "hi there")  // send string
tp_close(1)

works, but if there are more tp_send() one after the other I get no output!?!!

dosemu 1.1.1.x was working nicely

:(

regards.

Maurilio.


PS. On a side note, hogthreshold releases too much cpu when a clipper app is
running since runtime of clipper calls dos int-XX (I don't have it handy) to
retrieve time when it has nothing to do and this happens even during keyboard
input. Dosemu instead of releasing remaining of cpu slice does a sleep of a
certain amount of time, this causes sluggish keyboard input.
