In this example, OMEGA dials 1 949 555-2468, waits 6
seconds to allow a connection, and connects the line to port
4.

Second Dial Tone Method (Manual Connection)

With this method, the host computer calls OMEGA and waits for a
“second” dial tone from OMEGA. The second dial tone signals the
host to enter the DTMF tone that corresponds to an OMEGA port.

To enable this method, connect a laptop computer to OMEGA’s
DB-9 connector, start a terminal-emulation program such as
HyperTerminal, set up the program to use the parameters on page
62, and send the following command from the program:

\PR=1

.

When OMEGA is configured for the second dial tone method, the
host issues the following dial string:

ATDT<

phone number

>W,,<

port number

>

In this string:

<

phone number

>

is the OMEGA phone number (and area

code, if required).

W

indicates that the host is to wait for the second dial tone.

Each comma represents a 2-second pause.

<

port number

>

is the port number with which the host

wants to communicate.

is the pressing of the Enter key on your computer.

Example:

ATDT 19495552468W,,6

To switch from the second dial tone method to the time delay
method, use a laptop computer connected to OMEGA’s DB-9
connector to send the following command from a terminal-
emulation program:

\PR=0
