If you have the manual installing and using the VT330/340 it is in appendix E:
page 222.

pin	signal			Mnemonic
1	data terminal ready	dtr
2	tramsmitted data	txd
3	transmitted data return	-
4	received data return	-
5	received data		rxd
6	data set ready		-

I have only used this from VT330 VT340. I hooked up a modem to the MMJ port by
hooking a MMJ RJ11 cable to a RJ11 to RS232. the RJ11 adaptor is wired like
this
                        ---

I hope this helps.
