Yes*.
The footnote being that you can't send any byte sequence. Since the
radios use XON/XOFF flow control, those values are

Probably not the IC-V82 + UT-118. That rig has no serial port, AFAIK.

The V/U82s do have a serial port on them. It's down at the bottom of
the rig in the mo
Oh yeah, you really dont have much control over when the radio transmits. You
really dont even know if it has transmitted anything. If the channel is busy,
the radios will tend to hold off transmitting, so you dont walk all over
everything. But if two radios are both trying to send while some
With a tip of the hat to Dan (KK7DS) and Pete's (AE5PL) applications
that use the extra data space in the D-STAR DV signal, I don't believe
it was ever intended to be a reliable and transparent data service.
It's great to have a place to send some data along with voice data (and
its FEC), but
Would POCSAG be useful in place of FEC for short data exchanges ? de nu5d
