Did any one run faster than 57600 baud

[cmurray]

Was any one brave enough to run at 115200 baud this year.

If so what were you results? Any problems?

I am running at 57600 baud, 120 channels off of one port at 50ms timing.

I have one song where all 120 channels are blinking in unison at that 1/20 second interval and I am seeing dropout(missed blinks) at the end of the chain.

I am only running MAX232s but my total length is less than 100ft if that matters.

sounds like your at the limit. A RS485 converter may fix that.

I'm beginning to think that it is not a baud rate problem, or not solely a baud rate problem. I'm concerned that it is an OS scheduling problem, that events are delayed due to other activity (such as disk activity), and that these delays are causing serial buffer overruns (which I think would be most likely to truncate packets). However, I don't currently have a way to test it.

On Jan 4th I'll be harvesting all my PIC's and programming them all to 115.2Kbps and giving that a shot.

I can relate to problems as described by Phil. I am sure its my computer and not software or hardware. The missed packets vary. I have a fresh install of XP home running without other software. It does OK, only I notice the missing data.
