[WinLIRC] Infrared in managed code...simulating a 40khz Sony not possible?

[Scott H. <sc...@ha...>]

Hey guys,

 

I'm doing some work with Infrared and the Iguanaworks IR transmitter in C#
using some concepts from Winlirc.

I've been unable to push this thing fast enough.I can't get a full 96 cycles
(the 2400us header) out of it on a 3gHz P4 under no load. 

 

Is this just a "my very fast machine isn't fast enough" issue? That's
surprising, as the CPU isn't working.am I i/o port bound?

 

I'm using EscapeCommFunction and according to a number of profilers, that's
all my system is doing! 

 

Thoughts?
