I recently aquired a Netra T1 and am having some trouble with it. I
can plug my console cable into serial A on the back of the machine and
power on/off and reset the machine from LOM but I am getting no text of
any sort on my display.

The cable is good - I tested the cable on a newer netra just to make
sure.

I have been browsing the LOM docs in search of some command to
enable/disable display to the serial port but have come up with nothing
thus far.

Because the console is often switched to serial b I checked that out
too, but no luck.

The machine appears to boot up just fine despite all of this. Does
anybody have any suggestions for me to enable the serial ports or
otherwise fix this?

Thanks
