Then follow these steps:
1. Set the ANS/ORIG switch to ORIG.
2. Access TELCOM.
3. Press Find «(llJ) and type the code for the information service (IS in this case).
4. Press Call
(~)
after the number appears. You will not have to lift the receiver
when calling a host system in this way.
The Model 100 will "echo" a ringing tone or a busy signal (in which case you have
to redial the number).
After dialing, the Model 100 produces a high-pitched tone to indicate that it has
entered the Terminal Mode and the display changes to reveal the new roles for the
Function Keys.
For a detailed discussion of the role of the Function Keys in the Terminal Mode,
consult your owner's manual.
The Log-On Sequence
Once in the Terminal Mode (whether you entered automatically or manually), you
must comply with the log-on sequence to gain access to the services offered by the
information service.
Most information services will provide you with a User ID and a Password to serve
as confirmation that you are authorized to access a host system.
Detailed instructions for complying with the log-on procedure should be described in
your user's guide.
Experiment #2 Automatic Log-On
The Model 100 gives you the option to combine the Entry and Terminal Modes to dial
and log-on to an information service automatically. This is a practical, time-saving
feature, especially if you make regular use of an information service.
In this experiment we will create an automatic log-on sequence for the hypothetical
information service from the previous experiment. This automatic log-on sequence will
serve as a model for creating other log-on sequences for real host systems.
Let's assume that IS (Information Service) from the previous experiment specializes in
providing information of particular interest to Model 100 owners.
Let's assume that the log-on sequence for gaining access to this system consists of:
1. Sending two carriage returns.
2. Answering the prompt User ID.
3. Answering the prompt Password.
in that order. Your User ID. for this example is 9768,453 and your Password,
"Two-tone." Also, let's assume that after answering these prompts. IS asks you to
