[time-nuts] Lassen IQ receiver

[Morris Odell]

Thanks for the reply Bob!

Does this mean it's not possible to get two alternating NMEA messages from 
the same port? I have all the Trimble (IQ_chat and IQ_monitor) utilities and 
use port 1 to communicate with a PC using TSIP. I have port 2 connected to a 
microcontroller and I want to get both strings alternating with each other 
so I can translate them into a different serial code for a particular 
application. Alternatively the TAIP message TM has all the info I need in 
one sentence, but I can't seem to make it appear :-(

It's definitely an IQ not a SQ.

Thanks,

Morris
