[time-nuts] 4501 Netclock

[Bob Camp]

Hi

The pps pulse out of the TBolt is pretty narrow, the pulse stretcher is probably needed.

In addition to what's shown in John's instructions, you will need a link for the serial port. It's just like the link you set up for the pps port. The notes on the driver should show you what it needs to be called. gps0 is a pretty common name.
