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

[John Ackermann N8UR]

Check Startech (https://www.startech.com).  They have a range of RS-232 
and similar I/O cards and at least the last time I bought one several 
years ago, the chip emulated a 16550 UART and didn't seem to have more 
jitter than any other serial board I'd tried.
