Next: The Modem Commands Up: Using dip Previous: A Sample Script
Although widely used, dip hasn't been very well documented yet. In this section, we will therefore give a reference for most of dip's commands. You can get an overview of all commands it provides by invoking dip in test mode, and entering the help command. To find out about the syntax of a command, you may enter it without any arguments; of course this does not work with commands that take no arguments.
DIP> help
DIP knows about the following commands:
databits default dial echo flush
get goto help if init
mode modem parity print port
reset send sleep speed stopbits
term wait
DIP> echo
Usage: echo on|off
DIP>
Throughout the following, examples that display the DIP> prompt show how to enter a command in test mode, and what output it produces. Examples lacking this prompt should be taken as script excerpts.
