Johannes,
There's a third party multi-port adapter from DIGI international that we are
using to monitor 92 console ports from 1 PC. Hence, the driver only needs
one interrupt and the rest is purely transparent to our software... its just
like working with the ol' trusty basic serial COMs. Using a TCP/IP or
sockets to control multiple PC would complicate the whole thing. That;s the
reason we shift to LabView... to simplify the whole process. If were going
to do that setup, i'd rather go back to Visual C++ for more better control.
But still im hoping somebody would give me a definite answer whether it's
possible or not if it is, what's the alternative solution besides VISA.
TIA
John
