[time-nuts] OT : different Rx and Tx baud rate on same port

[Henry Hallam]

You could also consider making a simple gadget with your
microcontroller of choice, that presents an interface to the PC of a
fixed baud rate (perhaps 115200) and handles the weirdo split rates
for the GPS gadget on one or two of its other ports.
