# Z-SI/O Serial Interface Module Installation and Programming

The Z-SI/O Serial Input/Output Module is a “hardware based” serial interface which allows the Timex Sinclair 2068 Personal Color Computer to support the EIA RS-232C standards applicable to the 25 pin interconnection of Data Terminal Equipment (DTE) and Data Communication Equipment (DCE) employing serial binary data interchange.
