Communications parameters
There are four communications parameters:
❖
Modem speed—The speed at which the modem transfers
information. Speeds are measured in bits per second. Your
modem manual documents the speed of your modem.
❖
Data bits —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—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.
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.
