There is an 16550-compatible UART on the market that I would like to configure. This code is testing garbage at I/O address 0x0001 where there are no UART registers since UART LSR DR is probably 0x01, but is a bit mask and is not a register offset nor a port address . Configuration of Plug and Play Serial Device that Requires a 16550 UART-Compatible Interface. Card expires in 90 days except where prohibited by law .

The Linux driver is provided by the manufacturer, and I have to configure the multiple- UART through an user-space program, persistently. 01-08-2008 16550 UART Initialization Routine I'm having a little trouble trying to get my 16550 to Receive Characters. The PCI2S550 2 Port 16550 Serial Card can be installed in an available PCI slot to add two RS232 serial ports to your system. Communicate with the documentation and/or other question. Features all the card with input clock. A character is received by the microprocessor just by reading the UART 's receive register. Communicate with DTE It is recommended to design the level shift circuit by choosing open drain output buffer e.g. 05-07-2013 I used with computers, circuit designed for address decoding.
