Re: Mount does not stop Update
Dean Salman <cluster@...>
I do plan on updating all the chips needed, I think there is a Max
chip or something Howard told me about. I was in line with a new one
but got a good deal for this one, so spending some cash for the
latest stuff is something I do not mind.

because it is being overloaded with requests (such as positionrequests from

versions of the servo control software (not to be confused with theKeypad V4.12

the com ports kept the mount very busy. I do not recall whichversion
introduced the fixes. But I recall dealing with Bob Denny, RayGralak, and a couple
others on this. Bob e-mailed us "Port Mon" sessions that showeddropped
commands. We also replicated issues with the mount droppingmove/stop commands from
the keypad until the software was fixed. The reason the keypad isaffected
is because there were brief periods of time that the controller wasbusy
processing commands from other ports while the interrupts weredisabled. If the
controller is "out to lunch" longer than two characters (2.3mS),one character
could be ignored, which could make the entire commandunrecognizable and
therefore lost.the fixes
