initialization of COM port in C

com port init sequence

hi

could someone tell me the setup sequence of the PC com1 port? and also send a byte out. some simple c code without lots of constant names used but with direct raw hex numbers in the code.


what i need is address+data, address+data, address+data... setup sequence to make the UART core functional.
i have an FPGA project and I want to simualte the 16550 uart if it is working or not wihin my code. for the simulation, i will have to generate a signal assertion sequence (stimulus) as bus transactions and observe the TX pin in the simulator.
