Hi All,
Some modem support routines would send the init sequence over
and over periodically trying to re-init the Hayes modem.
This might explain the occasional 'drop outs'.
Lots of fun.

Hi Karl Heinz
I don't think this explains all cases of communications dropouts. I don't
think we're dealing with only one particular cause here. But this Modem
Manager can be the solution to at least a proportion of possible problems.?

Ah, finally an explanation for the communication dropouts that
actually makes sense. The "RF in?the shack" just did not explain
what I was seeing (and none of my other radios - digital or
analog - were affected by this.?
After making these changes, I was still not able to send CAT
commands to the QDX, but when I shut down WSJTX again, and
started up putty, I was able to see that the device was in the
terminal mode. After exiting, WSJTX was happy. I take that as a
confirmation that the modem manager was actually the guilty
party.?
