I did some more investigation. QT's wait functions are brain dead.
And I've got a couple other ideas to try.
Look at the bottom of this email at waitforReadyRead()...you ask for "are
you ready to read?" and inside it returns true if not ready to ready but
d->canWriteNotification is true.
So I moved the debug statement a little higher in send_command so I could
see the timing from send to receive better.
if (!no_debug)
{
#if WSJT_TRACE_CAT
qDebug () << "HRDTransceiver::send_command:" << message;
#endif
}
Then I added this based on the idea that you didn't get a reply if there
aren't any bytes available
while (!replied && --retries)
{
hrd_->waitForReadyRead (socket_wait_time);
auto mybytes = hrd_->bytesAvailable();
replied = mybytes > 0;
Here's a snapshot of the log where you can there are no bytesAvailble first
time even though the wait returns...but there are the 2nd time.
