If you're using a terminal I would use a straight-through cable rather than the null
modem. A computer to terminal set up is DCE to DTE in the eyes of RS-232 and so no cross
overs should be needed.
Actually, both the computer serial port and the terminal are DTE devices. A null
modem cable is required.
DCE devices assert CD for carrier detect -- modems, for example. On DTE devices, CD is an
input.
