Testing whether you can dial out

Having established that you can send commands to the modem, follow these steps to test whether you can dial out to a another site:

1. Enable the modem's speaker so you can hear it dial out and connect:
   
   ATM2

   (Use ATM0 to turn it off.)

2. Enter the following modem command:
   
   ATDTphone_number

   (This assumes that the connection can use tone dialing. Use the ATDP command for pulse dialing.)

3. Having confirmed that the modem can dial out, exit cu by entering:
   
   ~.

4. Dial into the other system using the appropriate modem control port, for example:
   
   cu -x9 -ltty1A phone_number

   The -x9 option generates useful debugging information.

   NOTE: Use dashes in the telephone number to indicate a pause while dialing. Do not use the comma (,) from the AT command set.

5. If the connection is successful and logging in is allowed on the remote machine, you should see a login prompt.
