Hi,

I am working on a StreamDevice interface for an Edwards STP turbomolecular pump and am having a problem with processing of one of the longer replies.


The problem appears to be that the ability to match a sequence of bytes for the "in" command when the bytes span multiple packets does not work for protocols that do not start with an "out" command (i.e. those linked to "I/O Intr" records).

  Is this the SCU1600 controller ? We have a number of them running. I
did have a problem with the controller occasionally delaying parts of
the longer responses (resulting in packet splitting) but I found that
a ReadTimeout of 150ms did the trick for us (100ms was just on the
edge). Other than that, I've had no problems using the controller.

Cheers,
       Richard
