ASIX Electronics Corporation Notice USB to LAN products 
Dear Customer:

If you got some problems on ASIX USB to LAN products, please download the How to identify authentic ASIX USB to LAN Products document to double check if your USB to LAN device includes an Non-authentic ASIX USB to LAN solution inside or not? If yes, please contact the manufacturer of your USB to LAN device to get proper drivers instead. ASIX DOES NOT GUARANTEE AND PROVIDE ANY SUPPORT FOR THOSE NON-AUTHENTIC ASIX PRODUCTS.

  Yes, I understand.

 MCS9865 -- PCI to Multi IO (2S+1P, 2P, ISA) Controller

MCS9865 is a PCI based Peripheral Controller. It supports dual-channel high performance Serial Ports, dual enhanced IEEE 1284 compliant parallel ports and an ISA style interface. MCS9865 is ideally suited for Desktop PC and Notebook applications, such as PCI / Mini-PCI add-in Cards for high-speed Serial / Parallel Port expansion.

The PCI interface of MCS9865 is fully Compliant with PCI Local Bus Specification, Revision 2.3. It supports five functions through single device.

On-Chip Serial Ports of MCS9865 support extended 16C550 UART mode and support serial speeds up to 16Mbps. MCS9865 has 256 byte deep Transmit and Receive FIFO for each UART. Deep FIFOs enable high serial speeds / throughputs and reduce CPU Utilization. Each Serial Port is compatible with industry standard 16C550 devices including Standard COM Port of Industrial PC, ASIX family of UARTs like MCS9901/ MCS9835 / MCS9845 / MCS9820 / MCS7840 / MCS7820 / MCS7720 / MCS7703.

The Parallel Port interface is an IEEE 1284 compliant SPP / PS2 / EPP / ECP Parallel Port that fully supports Centronics interface.
