rs485

Hi,

I am trying to use a rs485 com port on my computer running qnx neutrino and
it is not working as i expected.
The computer i am using is a nova8890:

Is devc-ser8250 the correct driver to use for 485 as well? Are there any
particular arguments I should give it to run 485?

The devc-8250 driver works just fine with RS-485 as long as your going
point to point OR your the master side of point to multi-point. If
your the slave side of point to multi-point, then I believe that you’ll
need to add some smarts to your serial driver.
