[Falkirk] 8 port serial card connections

[Craig R. Skinner]

To connect a Moxa 8 port serial card with octopus cable to an i386
serial port, do I need just a DB9 (2x female) gender changer, or a null
modem cable/mini adapter as well?

The octopus cable ends are all male, as are the serial/comm ports.

I've standard Cisco rollover cables to connect to my Sun servers RJ45
serial ports.

In my box'o-cable-crap I found a 3m female-female Belkin null modem
cable, booted the box & got console over the com port. I don't want to
buy more of those as the boxes are all in the same cabinet and the
octopus cable ends are long enough. Do you reckon the gender changers
would be sufficient?

Cheers,
