There are two things you need to know before you can connect to
another computer:
The communications parameters
The file transfer protocol (only if you're downloading or
uploading files)
The following sections explain what these mean.

Communications Parameters

There are four communications parameters:
Modem speed is the speed at which the modem transfers infor-
mation. Speeds are measured in bits per second. Your modem
manual documents the speed of your modem.
Data bits is the number of bits in one character. This number is
usually seven or eight.
Stop bits indicate the end of a character. This number is usually
one or two.
Parity is an error-checking method and will be set to even, odd
or none.
These parameters, except for the modem speed, are usually abbre-
viated and combined. Common examples are N81 (no parity, eight
data bits and one stop bit) and E72 (even parity, seven data bits and
2 stop bits).
You set each of these parameters in your communications pro-
gram. Each parameter must be set the same on both computers or
you won't be able to connect.

File Transfer Protocols

File transfer protocols are standards that govern how computers
transfer files between modems over a telephone line. Protocols
determine what type of error checking and data compression, if
any, occur during transfer. Based on a number of factors, some
