Equipment Employing Serial Binary Data Interchange RS 232 can operate at data rates of up to 20 kbps at distances less than 50 ft 15 2 m The absolute maximum data rate may vary depending on line conditions and cable lengths RS 232 is a single ended or unbalanced interface meaning that a single electrical signal is compared to a common signal ground to determine binary logical states The RS 232 and the EIA TIA 574 specification define two types of interface circuits Data Terminal Equipment DTE and Data Circuit Terminating Equipment DCE The serial host adapter is a DTE device Appendix C Asynchronous Communication In serial data communication individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character Data rate error checking handshaking and character framing start stop bits are pre defined and must correspond at both the transmitting and receiving ends Asynchronous communication is the standard means of serial data communication for PC and compatible computers The original PC was equipped with a communication or COM port that was designed around an 8250 Universal Asynchronous Receiver Transmitter UART which allows asynchronous serial data to be transferred through a simple and straightforward programming device The serial host adapter IC142C uses a much newer 16554 UART that also features buffering The IC190C R2 features an even newer 16854 UART
