The system to be called must be running Basic Networking Utilities (BNU) or some version of the UNIX-to-UNIX Copy Program (UUCP).
This procedure describes how to use the ct command to continue dialing multiple remote modem numbers until a connection is made or until a specified time has passed.
At the command line on the local system, type:
ct -w6 5550990 5550991 5550992 5550993
This dials the remote modems at phone numbers 555-0990, 555-0991, 555-0992, and 555-0993. The -w6 flag and number instructs the ct command to dial the remote modems at one minute intervals until a connection is made or until six minutes have passed.
Note: Type the phone numbers of the remote modems on the ct command line, either before or after the flag.
