Communication with another system by hardwire or modem

Use the cu command from your local system to accomplish these communication tasks:

  • Establish a connection to a specified remote system
  • Log in to the remote system
  • Perform tasks on the remote system
  • Switch back and forth, working concurrently on both systems

If the remote system is running under the same operating system, you can issue regular commands from your local system. For example, you can issue commands to change directories, list directory contents, view files, or send files to the print queue on the remote system. To issue commands for use on your local system, or to initiate remote command and file exchanges, use special cu local commands, prefaced with a tilde (~).
