I have observed the following behavior on Hayes Ultra modems, but
not on other modems including Hayes 9600 V-Series:

   My software raises DTR, and immediately begins sending AT commands.
   The modem takes from 0.5 to 1.5 seconds to begin recognizing
   or even echoing commands.  If DTR was never dropped, the delay
   is not present.  Please note that the modem is NOT slow due to
   DTR DROP, because DTR has been dropped for multiple minutes.
   The modem is just slow to get started after DTR comes UP.  MR is
   lit during the period of latency.  Also, SD is flashing during
   the period of latency, to match the data I am sending to the modem.
   It has been programmed with AT&F&C1&D3&W

If the modem is not "listening" then shouldn't MR be low?
Can anyone confirm this behavior?

Look closely at the return address.  It is nanovx and NOT nanovAx.
