PuTTY Instructions

Starting with Vista, Microsoft no longer includes HyperTerminal in Windows.  In order to debug whether or not your modem is capable of detecting caller ID, and what enable string it requires, you need to be able to communicate with your modem.  There are many possible programs you can use.  A good free option is PuTTY.  Here are some basic instructions for using PuTTY:

1. Download putty.exe here
2. Run putty.exe and choose the connection type of "Serial"
3. Enter in the COM port your modem is connected to.  (To determine this, you can open up your modem's properties dialog from the Device Manager, and look on the "Modem" tab.)
4. Click the "Open" button to open a connection
5. Continue on with the HyperTerminal instructions at step #4 (where you type "AT")
