#SERIAL COMMUNICATION PROTOCOL RS232 DATA MISMATCH SERIAL#

The serial digital data can be converted by modem, placed onto a standard voice-grade telephone line, and converted back to serial digital data at the receiving end of the line by another modem. One of the advantages of the RS232 protocol is that it lends itself to transmission over telephone lines. RS232 Serial transmission is beneficial for long distance communications, whereas parallel is designed for short distances or when very high transmission rates are required. In contrast, parallel communications require at least as many lines as there are bits in a word being transmitted (for an 8-bit word, a minimum of 8 lines are needed). Rs232 protocol transmission involves the sending of data one bit at a time, over a single communications line. Parallel communications are used mainly for connections between test instruments or computers and printers, while serial is often used between computers and other peripherals. Information being transferred between data processing equipment and peripherals is in the form of digital data which is transmitted in either a serial or parallel mode.
