3.11 Testing COM ports, Modems using checkmodems.exe
Checkmodems.exe can be found in the PhoneSweep directory. Because PhoneSweep controls each
modem directly, PhoneSweep can use COM ports from COM 4 up to and including COM 255.
Checkmodems.exe can scan all COM ports from 1 to 255. It can also be used to check specific ports.
After installing your Modems and any required Serial I/O port adaptors into your PC or laptop, and before
you run PhoneSweep for the first time, run checkmodems.exe to verify that COM ports are reachable
(Usually Windows assigns COM ports 5 through 8 for 4 port cards and COM ports 5-12 for 8 port cards).
• verify what COM ports your modems are on
• verify that modems attached to your computer are in good working order
• detect modems that support SCD
To test all COM ports, do one of the following:
• As a DOS line command: Open a MS-DOS prompt window and go to the PhoneSweep directory.
At the DOS command prompt, type: checkmodems.exe <Return or Enter>
• Double click the checkmodems.exe icon in Windows Explorer
• Select the “Check Local Modems” option from the PhoneSweep category of the Start->Programs
Menu.
If there is no hardware installed for a given COM port, or if another application is using it,
checkmodems.exe will fail to open the COM port.
If checkmodems.exe successfully opens a COM port, it then tries to turn on the speaker of a modem
connected to it and determine if it is attached to an active, working phone line. If a dial tone is detected,
checkmodems.exe then attempts to dial “55” on that port.
Checkmodems.exe displays its findings for each active COM port as it scans. For example:
