Re: detecting time gaps in real time data

[Ullrich Fischer <uf@xxxxxxxxxxxxxxxxxxx>]

You could have TS write something to an external file every tick and close 
the file every (say) 10 ticks then have a batch job running in a DOS box 
which uses a shareware program to check the size of a copy of the file to 
the most recent version every 30 seconds or so.  If two 30 second periods 
go buy without a change, the batch file could start beeping.   -uf
