The PCI-COM232/2 is a high speed, dual-port, asynchronous serial communications card for use in PCI-bus computers. The board is 117.5mm long and may be installed in any five-volt PCI slot in IBM compatible computers. A separate male DB9 connector is provided for each port. Each independent port supports RS-232 single-ended transmission/reception at baud rates up to 921.6 Kbps. An on-board crystal oscillator provides means for precise baud rate selection. The card is UART-type-16C550 compatible and includes a 16-byte transmit/receive buffer to protect against lost data in multitasking systems. Extensive software driver support is provided on CD. The card automatically configures with Windows Plug & Play functionality.
