Hi,
I tried bracketing my read of 'ACK' with 'MaxInput=1' and 'MaxInput=0', but it didn't help - still nothing in my PV.At them moment, you cannot change variables at run-time. The protocol starts and runs with the last setting. Thus this:
Well, that explains it.
In cases you have no terminator string but constant length input, using MaxInput saves you from using readTimeout as the line terminator. Thus you have no delay at the end of the input and no danger that two lines join to one in case readTimeout is too long.
OK, that's useful to know - this particular controller seems to have fixed lengths for each response type. Thanks, Richard
