Built-in modem function

The built-in modem is actually a computer expansion card that can be used by plugging into an expansion slot in the computer. It does not need to occupy the serial port of the computer. Its connection is quite simple, the telephone line connector is inserted into the "Line" jack on the card, and the other interface "Phone" on the card is connected to the telephone. When the modem is not used, the use of the telephone is not affected at all. The built-in modem needs to be disassembled during installation, and the interrupt and COM port are set up, which is cumbersome to install. This Modem takes up the expansion slot on the motherboard, but does not require additional power and cable, and the price is cheaper than the external Modem.
