This may be common knowledge here, but I was unaware of it (and, AFAIK, the DEC documentation doesn't point this out), so here goes... It turns out one doesn't need the fancy cab-kit to connect up to an 11/23+'s console. The headers on the card are completely compatible with standard DLV11-J connectors, and a DLV11-J cable can be used to connect up to an 11/23+ card. (One has to select the desired baud rate with the DIP switches on the card, of course.) I have verified this by trying it, and it worked. The cabkits merely allow one to select the baud rate at the console connector (via a clock generator on the cabkit, and the 'external clock' input on the serial interface). This implies that one should be able to plug a cabkit into an appropriately configured DLV11-J (external serial clock select), and select the baud rate via the switch on the cabkit. I haven't tried that, though.
