At this point the driver is populated with unlearned functions.
To learn driver functions:
1. Select those functions that are to be learned (see
figure 4-20). Then begin a learning session by pressing the
learn toolbar button. A series of messages and windows
will guide the user through the “learn” process,
instructing the user on how to aim the remote, what
button to press and when to release the button.
2. Save the driver by selecting File->Save, or you can add or
learn new functions.

User’s Manual.
Programmer’s Guide for the Telnet and Web
browser
Using the command/response table
The following are either Telnet (port 23) or Web browser (port
80) commands. There are some minor differences when
implementing these commands via Telnet or via URL encoding
using a Web browser. All commands listed below will work
using either connection method, but due to some limitations of
the Web browser, the encapsulation characters are modified to
make sure that the Web browser will properly handle them. All
examples in the command/response table shows the proper
implementation in a Telnet or Web browser session.
For Web browsers: all non-alphanumeric characters
must be represented as their hex equivalent such as %xx
where xx equals the two character representation of the
hex byte that needs to be sent (e.g., a comma would be
represented as %2C).
Telnet Web Browser
Escape (Hex 1B) W [must not be encoded]
Carriage Return (Hex 0D) Pipe Character
(
)
[must not be encoded]
When using these commands through a Web browser, the URL
reference is used below to shorten the examples. This would in
practice be the full URL of the control interface and Web page
reference including all path information
(e.g., http://192.168.100.10/myform.htm).
To send any of the commands using a Web browser you need to
prefix them with the full URL followed by ?cmd= See URL
Encoding later in this chapter.
With Telnet you can use either the “Escape” commands
or the “W” commands, and the carriage return or the
pipe character. With the Web browser, you are required
to use the “W” commands and the pipe character.
In either method {Data} = Data will be directed to a specified
port and must be encoded if non-alphanumeric.
The table on pages 4-23 through 4-29 lists the commands that
the IPL T interface recognizes as valid, the responses that are
returned to the host, a description of the command’s function,
or the results of executing the command.
Upper and lower case text can be used interchangeably
except where noted.
Symbol definitions are shown below. An ASCII to HEX
conversion table is also provided in figure 4-21 (below).
