Q: data in the same manner? E.g., printers attach to computer through paralell port (sometimes). Is there a UART to convert this dara to parallel?
A: It sounds like you're reading about technology from 1990. UARTs and it's relevance have no place in the 2000 era of digital technology. UART, baud, serial, parallel and modems have died with the end of the analog era of communications. Everything in 2008+ is digital and full duplex.
