Hi,

You can limit the scope of a checksum like this: %1<xor8ff>

A checksum like %A.B<...> ignores A bytes at the beginning and B bytes
at the end.

  and this works perfectly, thanks (and thanks to Florian as well).

For fixed-length input you can use maxInput=number_of_byes; instead of a
terminator.

  I tried bracketing my read of 'ACK' with 'MaxInput=1' and 'MaxInput=0',
but it didn't help - still nothing in my PV.

Many thanks,
     Richard
