[time-nuts] Re: Ryzen mobos with serial port for Garmin GPS?

[Andy Talbot]

Use FTDI USB serial ports - you can't go wrong with them.

I have, at the last count, used something like 200 of their FT232 device in
one form or another on the shack PC.   I know that, because device manager
has registered up to COM200.  Every time a new one is plugged in, a new COM
port is set up.
