to receive data from the computer, and then use
that information to answer printer-specification questions in the application. If your
application doesn't ask for your printer's specifications, use the information to reconfigure
the printer port by using the Control Panel Program. If you're sure your printer specifications
are right, take your cable to your authorized Apple dealer and make sure it's the right kind.
Trouble With the Modem
Every character appears twice on the screen when you're sending a message.
Your computer is echoing every character you send on the screen, and the other
computer is echoing every character it receives back to your screen.
Change the Echo setting to No by using the Control Panel Program or the communications
application.
A line of meaningless characters appears on the screen when you send or receive
messages over phone lines.
The computer on the other end of the phone line is sending information to your
computer in a form your computer isn't set up to receive.
You're using either incompatible bauds or incompatible data formats (the wrong
number of data bits or stop bits, or the wrong kind of parity). Check the documentation
furnished by the information service to see what specifications the other computer is using,
and then change the way your computer is set up to
exchange information by using your communications application or the Control Panel Program.
Characters are lost during information exchange.
There is too much distortion on the phone lines to transmit information at
the speed you're using.
Change to a lower baud, if possible, on both the sending and the receiving end.
Information sent through the modem doesn't appear on your screen.
The other computer isn't echoing information back to your computer. It's a half-duplex modem.
Change the Echo setting to Yes by using the Control Panel Program or the communications
application.
Appendix C - Apple II Family Differences
Every enhancement of the Apple II computer has been designed to be as compatible as possible
with earlier models.
The Apple IIgs has more memory and more features than any of the models that came before it,
but those features are implemented in such a way that you can use most of the software
developed for earlier machines. Keep in mind, though, that if an application was developed for
earlier models of the Apple II, it won't take advantage of the features of later models.
