1.)  Install the Hayes compatible (modem that responds to 'at' commands) ONLY on Port B (ttyb) 
     of either the Sun Fire V120 or V100. 

     Note: There is some concern about Port A providing a DTR signal, so use Port B.


2.)  Configure the modem cable in accordance to the pinouts below. 
	RJ45 Signal Modem (DB25)
	1 RTS 4
	2 DTR 20
	3 TXD 2
	4 Sig Grd 1
	5 Sig Grd 7
	6 RXD 3
	7 DCD(DSR) 8
	8 CTS 5

3.)  Using Admintool, configure the modem for bi-directional. 
     If unable to run Admintool, add the following ttyb line to /etc/saf/zsmon/_pmtab. 
     Restart SAC.
     # VERSION=1
     ttyb:u:root:reserved:reserved:reserved:/dev/term/b:b::/usr/bin/login:120:38400:ldterm,ttcompat:login\: ::dialup:n:#Modem - Bidirectional

4.)  Using TIP, configure the actual modem for dial-in. 
     This will also sync the modem with the computer to avoid garbage logins.
	# tip -38400 /dev/cua/b
	Connected
	at
	ok
	at&f (reset to factory)
	ats0=1 (AutoAnswer on 1 ring. that's a zero)
	ok
	at&c1&s1&d2 (sets DCD and DTR to transition)
	ok
	at&w (write permanent)
	<cr> ~ . (to exit TIP)
Done.
