If exactly two people participate in the game, they live in the same city, and at least one of the players has an unlimited landline phone, it is not necessary to use the Internet for communication. You can also play over a regular telephone network.
Instructions
Step 1
Get a regular analog modem and ask a second player to do the same. Modern ADSL modems will not work. Each of the devices must be designed to be connected to an interface that a computer has (for example, a modem designed to be connected to a COM port or installed in an ISA slot cannot be interfaced with a modern machine). As a last resort, you can use USB-COM converters.
Step 2
Connect each of the modems directly to the telephone line. If you already have an ADSL modem, leave it in place, like the splitter, and connect the analog device in parallel with the telephone sets. Do not touch the exposed line wires - at the time of the call, high voltage arises on them.
Step 3
Using a terminal program, find the port to which the modem is connected. Issue the ATZ command - if you get an OK response, the modem is found. Call the second player, ask him to do the same, then enter the command ATS0 = 2, and then hang up. Issue the ATDPnnnnnnn command, where nnnnnnn is the other player's phone number. When the modem calls him, he will see the RING message. After two calls, his modem will pick up the phone by itself, and you will see the CONNECT message. Type something on the keyboard - the second player will see the same thing. If he picks up anything, you will immediately see it.
Step 4
After making sure that the connection is working, press the plus key on the numeric keypad three times in a row, and the modem will enter the command receiving mode. Enter the ATH0 command and the line is free.
Step 5
Launch the game program, enter the modem connection setup mode (the way to enter this mode depends on the program), then enter the name of the port to which the modem is connected and the phone number of the second player, in front of which put the Latin letter P. Call the player and ask him to switch the game to receive a modem call (how to do this also depends on the game). Hang up the handset and press the connect button available in the game program.
Step 6
After completing the game, click on the disconnect button or select the corresponding item from the menu. After that, both players must send the ATS0 = 0 command to their modems using the terminal program so that they do not respond to incoming calls.
