- BZZZZT! Nope. You need a "null modem cable". This is an RS-232 cable
- with several connections swapped (notably the SEND and RECEIVE pins) and
- others shorted together. This allows two DTE (Data Terminal *Equipment*)
- ports to talk to each other. The standard RS-232 cable is meant to connect
- a DTE port to a DCE (Data Communications Equipment) port. The difference
- between the DTE and the DCE is that the DTE is assumed to control the
- communications across the line. Thus, a PC would be a DTE and a modem
- would be a DCE.
-
- (Note that modems have two modes, ANSWER and ORIGINATE, which allow them
- to do the same SEND/RECEIVE swapping that a null-modem cable does.)

- I always had to specify it to our school's system as an 'h19'. I don't
- know if it's VT52-compatible.

- This should be settable with some DIP switches on the back.

-
- It would probably be better to add a line to your /etc/inittab file:
-
- ttys2:vt52:/etc/getty 9600 ttys2 (for the standard getty)
- or
- ttys2:vt52:/etc/getty ttys2 9600 (for use with getty_ps)

-
- I think you would, but I'm not sure how you'd best go about it.
