Dialup/Dialout Modem

• Make /etc/uucp/oldconfig link
  

  	   mv /etc/uucp/oldconfig /etc/uucp/oldconfig.junk
  	   ln -s /etc/uucp/oldconfig /etc/uucp
  	   

• Create /etc/uucp/Devices

  	   # /etc/uucp/Devices 
  	   # Direct connections with 'cu -lcua1'
  	   # In this case cua1/ttyS1 is being used. Change to cua0 for ttyS0.
  	   Direct          cua1 -         38400   simpleout
  	   Direct          cua1 -         38400   simpleout
  	   Direct          cua1 -         9600    simpleout
  	   # Auto dialout
  	   DIALOUT         cua1 cua1      38400   dialout
  	   DIALOUT         cua1 cua1      9600    dialout
  	   

• Create /etc/uucp/Dialers

  	   # /etc/uucp/Dialers
  	   simpleout "" "" ATs2=128s12=255s0=0 OK
  	   dialout   "" "" ATE1Q0&C1&D3&Q5S2=128\sS10=200\sL0 OK atdt\T CONNECT
  	   

• Create /etc/uucp/Systems

  	    # /etc/uucp/Systems
  	    # Create your names (work,home) and phone numbers (5551212) 
  	    # for auto-dialing outbound calls with cu(1) here, eg. 'cu work'.
  	    work    Any DIALOUT 38400 5551212
  	    home    Any DIALOUT 38400 5551234
  	   

• /etc/inittab Configuration
  • Add the following line to /etc/inittab

    	   s0:2345:respawn:/sbin/getty ttyS1 38400 vt100	# Change ttyS1 as needed
    	   

  • Restart init

    	   kill -1 1
    	   

• Modem Configuration
  The idea is to program the modem to auto-answer, and save this state so that the modem automatically auto-answers, even after being power-cycled:
  

  	   cu -lcua1	# Connect to modem with cu(1)
  	   ATS0=1	# Set modem to auto-answer
  	   AT&W		# Commit setting to EPROM
  	   ~.		# Exit cu(1)
  	   

• Testing
  You should now be able to dial in (modem should pickup and answer, and login: prompt should be presented), and you should be able to dial out with 'cu -cua1' or 'cu work'.
