Summary

Starts a listener in the startup shell.

Package

lispworks

Signature

start-tty-listener force => process

force

A generalized boolean.

A listener process, or nil .

Description

The function start-tty-listener returns a process that runs a listener read-eval-print loop connected to *terminal-io* .

If force is nil , then start-tty-listener checks if the default listener process is alive or if there is a live process with name "TTY Listener". If such a process exists, start-tty-listener simply returns nil and does not start a new process. If no such process exists, or if force was t , then start-tty-listener starts a new listener process named "TTY Listener", and returns it.
