CHAPTER 1 The PCCOM PCI bus 2 port adapter is an 32 bits PCI bus
board with Plug and Play (PnP) features, it provides two asynchronous
serial communication The PCCOM PCI bus 2 port adapter is particularly suited
to facilitate the connection of terminals (VDUs) in multi-user
operating
systems. The PCCOM board may be installed in any Pentium or
hardware compatible systems. The PnP features let hardware
configuration for IRQ and I/O address is detected by BIOS
automatically,
you don¡¦t need set switch and jumper. Since most of the computer has its own COM1 and COM2, the
PCCOM PCI bus 2 port adapter can be configured from COM4. On board 16550 chip provides two 16550 functions
which
contains 16 bytes FIFO buffer for each 16550 ports. There are two kinds
of mode can be choose, one is normal speed mode that its baud rate up
to
115200, another is high speed mode that its baud rate up to 640K. |
