Modems and COM Ports

By Todd123 ·
I installed a modem and the drivers are installed correctly. When I try to dial out I do not get a dial tone. The modem states that it is connected to COM port 4, but in the Hardware/Device Manager under COM Ports/LPT only COM1 and COM2 are listed. My question is how do I get the modem to use one of the COM ports that are listed in the Device manager??

Thanks for any and all help to this question.

Most modems use a virtual COM port.

That is, your modem uses a software COM port so that the modem software has a COM port to use.

COM 1 and COM 2 are most likely RS-232 serial ports on your motherboard.

Unless you are using an external serial modem, your modem cannot use either of these ports to communicate.

The most common cause of no dial tone with a modem is that the phone line is plugged into the wrong jack on the modem.

Virtual COM

by tiagovalebarbosa In reply to Modems and COM Ports

I'm having the same problem using the modem sharing!

I have a modem instaled in Windows 2000 SBS and i've got the modem sharing server instaled there. I'm sharing the COM where the modem is conected.

My problem starts when i try to install the modem in another computer in the network.

I install the client service of the modem sharing, and configure the service by open a virtual COM (COM3) and gives it a path to the server where the COM is shared, but when i try to install the modem by using the virtual COM the system don't detect the COM created (COM3).

If some one knows anything please tell me something.
