Re: [ts-7000] Re: TS7800 hiccups around 6:28am everyday

Thanks, I'll keep an eye out for this.

What kinds of hiccups are you experiencing?  What are the specific symptoms?
What baud rate are you communicating at?
Are you using the RTS / CTS lines on TTYS4 -- I've had issues with those lines (using PPP over that port in particular).


Just out of curiosity, what is your edge device that you're reading via serial?

I'm using a TS7800. The data acquisition is on com3 (/dev/ttts4).

I'm also getting some hiccups at various times throughout the day, but
consistently at 6:28am.
