If I power on my DN300 in service mode with a terminal connected to one
of its serial ports (the terminal being my Amiga with some terminal
software), the MD does recognize the terminal as the primary
communications device just the manuals say it will.

The problem is that I can't get it to use the port for communications
at any level above the MD.

For example if I "EX AEGIS" (this is SR9.7), I get the messages about
the program being loaded, but I never get back a Phase-II prompt. The
only thing I can do is break back out to the MD again by using the
ESC key. Same thing happens with other programs like INVOL.

Is there some way to make this thing "think" it's really a DSP rather
than a DN, so I don't need to use the node's screen at all? I considered
pulling the display board but the manuals say that the Phase-II won't
run at all without a functional display board in the machine.

The display is on its last legs and I'd like to be able to just pull
the display fuse and bring the node up via the serial port as a server,
making it a DSP80 or DSP90 of sorts. CAN THIS BE DONE?

Any suggestions/help appreciated...
