Compex SRX1224

Some notes on Compex SRX1224 switch.
You plug an null modem cable there, and it does not work? Right?
That's easy. You need the straight, non-null-modem cable! And you need some DB9F-to-DB9F direct converter.
As for switch itself, it is 100Mbs switch, managed from console only, without 802.1Q, just port switch.
UPD: also, for the Nortel/Baystack 325 and 425, you need straight cable, too. But it's a very different device, full of vlans and other useful features.
