Baud Modem Operation
General
A.ll
Appendix A
Modems are a combination of hardware and software that let computers
talk to each other over telephone lines. Using the built-in modem, your
computer can call data bases, electronic bulletin boards, and other personal
computers.
Your modem has a unique feature: you can use the Phone Directory
for automatic dialing of voice calls, not just modem (computerized) conver­
sations. Throughout this section, we'll use the term voice calls to mean
regular telephone calls that you let the computer dial and/or time for
you. The calls which are carried out through the keyboard and display
will be referred to as modem calls. With these, your telephone stays hung
up.
When you're in the modem mode, there are two screen displays you
will see. One is the Directory Display which you'll use when you choose
a number to dial. The other is the Update Display which you'll see when
you add, remove, or change a number.
You can enter the modem mode from other modes. For example, if you're
running a business program or working with MS-DOS, all you need to
do is press the Phone Icon. When your call is finished, press the appropri­
ate icon to return to where you were. (If you made a modem call, it
will be necessary to press the Phone Icon first to return to the Directory
Display to hang up.)
The following keys are used to move the cursor around both the Directory
Display and the Update Display:
Return
-
Press this key to move down through the directory list,
one line at a time.
Up and Down Arrow Keys
-
Press this key to move the cursor
up and down a line at a time. When the Shift key is pressed at
the same time, it moves up and down a screenful at a time. The
down arrow key can be used interchangeably with the Return key.
