vrf VEE serial Communication BUG...

Question asked by robert on Jun 27, 2003
I reported problem number one to HP (their name then) three years ago.  And
that was prior to the VEE 6 release.  The work around was to use a wait
object between the I/O objects.  By the way, this was not a problem in VEE
4, it worked as expected.

A personal opinion:  Things do not get fixed unless they affect the "right"
person.  Apparently Agilent does not use its own products enough to be
affected.

> BUG#1:
> There is an obvious BUG in Serial Communication with VEE.
> If there is a wait transaction between two serial communication
transactions (with no EOL) then the
> position of the time delay is ignored and all the commands are send after
the delay.
> This caused a hard to find problem for me while I tried communicate with a
serial device and took a long time

result; i.e

"" (that means nothing) at the

character at the end (We send EOL but EOL is nothing, so nothing must
change )  everything was OK.

character end of trancsactions, is quite baffling with VEE!!!
