RE: Using Minicom with /dev/ttyU0

["Charles L. Nelson" <charles%embsyspro.com@localhost>]

Hi Again,
I have NetBSD-4 running on a new HP laptop that does not have a serial port.
Therefore the only "real" serial port available is the one that I am using.
Also the dmesg output does not indicate any errors.

I've had weird behaviour with USB-2-serial adapters even under Windows
with one of our DNC programs. I think one should first prove the
viabity of the platorm using *real* serial port, eventually trying the
USB conversion later. The cabling to the device also could be an
issue, adding loopbacks at the PC side could help (try 1+4+6 and 7+8
on a DB9).
