Communications parameters
There are four communications parameters:
■
Modem speed - The speed at which the modem transfers information.
Speeds are measured in bits per second.
■
Data bits - The number of bits in one character. This number is usually
seven or eight.
■
Stop bit - Indicates the end of a character. This number is usually one
or two.
■
Parity - An error-checking method, which will be set to even, odd, or
none.
Communications parameters, except for the modem speed, are usually
abbreviated and combined. Common examples are N81 (no parity, eight
data bits and one stop bit) and E72 (even parity, seven data bits and two
stop bits).
You set each of these parameters in your communications program. Each
parameter must be set the same on both computers or you will not be
able to connect.
To check your modem’s settings and communications parameters:
1.
Click the
My Computer

operating system displays your modem’s Properties dialog
box. This dialog box contains information about your modem
configuration and status.
File transfer protocols
File transfer protocols are standards that govern how computers transfer
files between modems over a telephone line. You do not really need to
know anything about specific protocols-just make sure you are using the
same protocols as the computer with which you are communicating.
