Using TCP/IP Sockets from JavaScript

The directory called sockets within the ATP examples directory contains several

examples that show sockets script structure. The file

/examples/sockets/sendmail.atp shows how to use the ATP sockets

interface to send an electronic-mail message using the Simple Mail Transfer Protocol

(SMTP).

Selections from the file sendmail.atp are displayed with accompanying text below. Print

that file or display it on screen if you need to see the complete code.

The example script in Example 3-8

contains only enough HTML to permit invocation

from a browser. No HTML would be needed to run the script in an OSS shell

environment.

The code starts with error handling in Example 3-9
