Hyper Terminal into a Modem and Make a dial

Here is a sample session to connect HyperTerminal to a COM port to a modem. The progression described in this section works on most Windows systems.

1. From the Start menu, point to Programs > Accessories, and select HyperTerminal.
   Note: If HyperTerminal does not appear in the menu, you need to install it from the Windows CD-ROM.
2. Double-click the Hypertrm.exe file. The Connection Description dialog box is displayed (see Figure 1).
   Figure 1 – The Connection Description Dialog Box
   
3. Select an appropriate name and icon.
4. Click OK.The Phone Number dialog box is displayed (see Figure 2). HyperTerminal assumes that you want to make a call, so it prompts for the phone number. From the drop-down list, select the desired COM port.
   Figure 2 – The Phone Number Dialog Box
   
   When you make a selection, the relevant Port Properties dialog box is displayed.
5. Set the COM port to 115200 bits per second, because that is the fastest speed modems can communicate over the data terminal equipment (DTE) link (see Figure 3).
   Figure 3 – Set the COM Port to 115200 Bits Per Second
   
   Note: This speed is not the connection speed the modems use to talk to each other. This is the speed that goes across the async modem cable between the PC and its modem.
6. Click OK.
   A terminal window is displayed.

Here is an example session that uses the ATI commands numbered 3 through 11. This example includes what was entered and the responses from a modem in one of Cisco's labs:

Here is the output from a connection to one of Cisco's test systems. First, enable the speaker and DCE rate information reporting:

atw2m1
ERROR

As it turns out, w2 is not necessary on US Robotics modems.

OK 

Next, dial into a static lab:

NO CARRIER

The normal connection seems to fail. In this case, it is a noisy line, so set the modem to factory defaults (&f), turn on the speaker (m1), and cap the modem at 28.8 (&n14) with the at&fm1&n14 command:
Try to dial again. If the connection is successful you will see:
