Altera Nios UART communication

[Jasmine Hau]

Hi, can anybody tell me how to send/receive a multi-bit (Eg.160-bit or
512-bit)data between Altera Nios FPGA board with Visual Basic Program
running on PC? Do i need any handshakind signal between the C source
code which will downloaded into the embedded system with the VB
program?
And, can anyone recommen me any website to gain information
regarding serial port communication interface and C source code of it?
Thank you very much.

No, you don't need to use the modem control signals. Books exist on
RS232 and Visual Basic, though I haven't read them. Try amazon.
You'll need to decide if you want a protocol (e.g., a checksum or CRC
at the end of your packet), or if you just want to accept the first N
bytes received.

google. Also, look for application notes for UARTs.
