Epson 4SLC2-50 - Manual (Page 67)

Appendix B provides a summary of the modem’s features and
internal command set. You need to use the fax/modem’s built-in
set of commands only if you are not using the telecommunications
software package. Each communications program provides its
own set of commands that you will use to control the modem
instead of the built-in set.
Note
Be sure to read the modem FCC information at the front of this
manual to avoid electrical interference problems.
Adding Memory Modules or a Numeric
Coprocessor
The sections below describe how to add memory to your computer
and install a numeric coprocessor. To access the sockets for these
options, you need to remove the keyboard.
Caution
It is best to have your Authorized Epson Servicer install the
memory module or a numeric coprocessor for you because they
can be damaged easily if installed incorrectly. If you prefer to
install them yourself, carefully follow all the instructions in this
section. If you have any questions at all, please contact your
Authorized Epson Servicer or call the Epson Connection.
