How do I receive and transmit UART signals with my PC?
If I have access to a UART communication signal on a board, both the TXD and the RXD, is there anyway I can interface this with my PC to both read and interpret these bytes from the Transmit, and even produce my own signals and feed them through the Receive? Can I just cut open one of my old 9-pin serial cables, connect the Receive and Transmit data lines to the UART TXD and RXD, and just connect this to my PC? Is there then software which can interpret and produce these signals?
Am I just way off in my question to begin with, and misunderstanding something fundamental here?
