Now on RHL 9, pilot-link-0.11.5-4, but I have been using it since the RHL
7.x days (I think RHL 7.1, but that was a while ago, so can't quite pin
that one down). RHL 8.0 - most definitely.

Here is what I see in /var/log/messages when I plug in my BAFO cable:

Jun 12 02:36:15 wookie kernel: hub.c: new USB device 00:1d.1-1, assigned

So the port to point at is /dev/ttyUSB2 (in this case). Should just work.

p.s. I just googled around, and found that the reason why most of thee
these cables should just work is because they are all based on the
Prolific PL2303 USB to serial bridge controller
(http://www.prolific.com.tw/fr_pl2303.htm). So if you get a cable that
uses this thingy, you are apparently safe.
