This is in Appendix D of the 3b2 Owner/Operator Manual.

Looking at the console modular jack on the rear of the 3b2 (the locking tab
should be down) the pins are numbered right-to-left 1 to 8.

	8-pin			25-pin			25-pin
	modular			RS232			RS232
	jack			for terminal		for automatic dial
				or printer		modem

	1 Prot Grd		1 Frame Ground		1 Frame Ground
	2 Reserved		4 Reserved		5 Reserved
	3 TXDO			3 Transmit data		2 Transmit data
	4 DTRO			8 Data terminal ready	20 DTR
	5 RXDO			2 Receive data		3 Receive data
	6 DCDO			20 Data carrier detect	8 DCD
	7 SIG GRD		7 Signal ground		7 SG
	8 Reserved		5 Reserved		4 Reserved
