Chapter 20 THE FIRST CONNECTION Telecommunication using computers and modems is a simple task. You need only observe a few - important - parameters. This example shows you how to log into a BBS using the terminal program which is included with Microsoft Windows 3.x. As a Windows component, this simple terminal program has been widely distributed and offers the basic features of a telecommunications package. Many other programs are available which offer many more options. However, even with those programs, the basic steps are the same. Therefore the steps presented here should be helpful to all users. Before you start, make sure that all cables are installed as described in chapter 3. Be sure that your serial cable is not a null-modem cable. Nullmodem cables are useful in direct computer to computer serial connections only. 1) Start the terminal program. It usually resides in the Applications folder. 2) Type AT from your keyboard and press the ENTER (or RETURN) key. You should see the characters you just typed in the terminal window along with the modem message OK in the line below. If you don't see anything, check the connections, reset the modem and try step 2 again. If anything else appears in the terminal window, some parameters in the modem may be misset. Reset the modem and redo step 2. If you still see anything else, some of your terminal program's parameters may be misset. We will show you how to take care of this now. 3) From the menu Settings, choose the entry Communications. In the dialog, set the following values: Baud Rate: Data Bits: Parity: Flow Control: Stop-Bits: Port: 19200 8 None Hardware 1 COM1 If your PC serial port is equipped with a UART 16550, these settings should work fine. If not, you may have to use a lower transfer rate. Please refer to chapter 21 for more solutions to hardware problems, and how to work at high speed. 20-1
