Fastest Internal Modem . US Robotics PCI Modem 0637

This 56K internal modem is similar in size to the earlier ISA versions that were Plug and Play (PNP), or used jumpers to set the COM port and the IRQ number. The 0637 modem is only PNP, there are no jumpers to select the COM and IRQ settings. This modem has a socket so it can be connected to some audio cards. You can find modem drivers for this modem on the Internet. This is a Data / Fax modem. It connects over telephone lines to converse with another computer. The Fax capability allows it to send and receive facsimile messages without a separate dedicated fax machine. But a fax machine is better with a dedicated telephone line as it won't interfere with voice communications at the same time. It is easier to use for the average person.

Internal modems are inserted into the appropriate slot after the power is off and the cover removed. When the Windows operating system starts it will recognize the added hardware. You can either let Windows search for the driver software, or direct it to the floppy drive or folder on your hard drive. The drivers (mdm3cvm1, wmwave) for this "56K Voice Win" modem fits on a floppy disk, or CD. You will need added software to support sending and receiving faxes on your computer. Some software will handle pages that have been read into the computer via a scanner.

This modem can handle the top speed of local telephone lines. If you are further than 3 to 5 miles from the telephone switching station the top speed will probably be lower. Static on the lines can affect transmission speeds. The long wires act as aerials to pick up radio transmissions or electromagnetic disturbances. You may also notice a drop in speed during heavy rains. Thunder and lightning can affect the lines. Hardware modems are inherently faster than a Windows modem because there is no operating system use.

CD-ROM drives are designed to meet international standards. You can replace most any CD-ROM drive with another, even from a different manufacturer, and it will still work. Not so with modems, sound cards, and video cards. They usually need special driver software that is unique to that model. IDE hard drives have the same interchangeability as long as the size is supported by the computer's BIOS and the jumpers are set correctly.
