[Xastir] Serial tnc and Prolific USB adaptor

[KA7O]

David,

I use a Prolific USB to serial adapter with my KPC3+ and it works very 
well in Xastir for me. I run Xastir on Fedora and CentOS.

Couple things to watch:

1 - bring up a terminal shell
2 - put the USB adapter in a USB port
3 - as root, type: dmesg <enter>
4 - near the end of all the lines of info, you should see several lines 
that describe how the adapter was detected and how it was setup. One of 
those lines will tell you what it's 'serial' port is.

For me - it's often /dev/ttyUSB0 - but on occasion, it'll show as 
/dev/ttyUSB1

You can also use minicom -s <enter> to configure the serial port, remove 
all the modem crap and then 'exit' to minicom and access the serial 
device directly. Just another way to verify where it actually is.

I put whatever the current address is in my interface config for serial 
TNC in Xastir and away it goes!

HINT: as a matter of course, do not reboot Linux! There is usually NO 
NEED to do this, short of a kernel upgrade.

I also use a GPS receiver with a built in USB to serial adapter, 
depending on what is plugged in when or what's plugged in when I power 
the thing up, my GPS receiver and TNC port can all appear on a variety 
of ports. I've seen them go as high as dev/ttyUSB4 once.

G'luck!
Tate, KA7O
