vrf DAV(interface event) question

Question asked by VRFuser on Nov 9, 1999
Well I have found a solution and also discovered another way to flush
the serial buffer.

By accident another person working with me tried the "Execute Reset"
to flush the serial port buffer and it worked. I know I have tried it before
and
it did not work and I have read many an email saying it does not work.

The difference this time is that on Windows 98 it does work. I do not know
about Windows 95. I know it does not work on NT.

So now I have four instances of the same program running using 4 different
com ports that get selected by four command lines that each use a
different vee.io.

Some days you just get lucky.

Thanks for all of your suggestions.
