Recently I posted about a serial port problem. The gist of the problem
was that serial ports were going dead, requiring a reboot to activate them.
In the course of diagnosing the problem, we discovered that "pdisable -a"
did NOT drop DTR to the modems... SOMETIMES. We did not have HUPCL
in LOGMODES for the port, but we did have it for RUNMODES. If someone
had not logged-in on a port, pdisabling the port did not drop DTR.
In other words, if HUPCL is not set (i.e. "stty -hupcl"), then
pdisableing a port does not drop DTR. I assert that this is a bug.
True or false?

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