Flex and nulls #1

Closed Ian-May closed 9 years ago

Hi Neal - there are at least 2 ways to get rid of the nulls in FLEX. The best is to modify the byte at location $CC05 - TTYSET Null Count. The default is 4 - set it to zero. The second method is to use the "TTYSET" command in your FLEX startup.txt file (or anytime on the command line). TTYSET,NL=0 will set zero nulls. The downside of this method is that it will have already printed some nulls before it gets this far. Cheer, Ian.

Hi Ian, thanks for the suggestions. I have now learned how to use FIX and documented a flow for using that to do the patch, which I can see is much neater and faster than the startup file. Neal.
