HP53131A RS232 question

I reconfigured for TI with +.7V level 50Ohm and I get a good count.
With a TI of around 43milliSec between two 1pps signals the display is
updating every second.
However if I turn print on the display update slows way down and no
longer displays consecutive counts!
I know I had this working once!!!
Should I be using some other function than print?
I just want the hyperterminal to take and log the data!

Hi

I don’t typically use 50 ohms with logic signals, but other than that I
don’t see much different between what you describe and what “just works”
for me on multiple 53131’s and 53132’s. About the only weird thing I can think
of would be a baud rate so slow that the string does not complete. I
don’t think that the counters will go that slow …..

I never use any form of hardware or software pacing, A “send after timeout”
might explain some weird stuff.
