Russ,
I am using 2 Lava Computer mfg Inc Lava Octo 8 port cards. It seems
that only the first 6 serial ports on the first card are recognized.
They use the standard serial driver (Digi has it's own drivers, so they
act differently). Which brings me back to the original question, is
there a way to bump up the standard serial driver number with out a
recompile?
It was also mighty nice of you to pop in 4 serial cards for testing,
many thanks!!!
The parent to your reply talked about passing a parameter to the driver,
but if I am not mistaken the driver is not loaded as a module (I could
be wrong though)
Some more helpful information follows:
The modules that are loaded are:
