What is RS232?  
"In telecommunications, RS‐232 is a standard for serial communication transmission of data. It formally 
defines the signals connecting between a DTE (data terminal equipment) such as a computer terminal, 
and a DCE (data circuit‐terminating equipment or data communication equipment), such as a modem. 
The RS‐232 standard is commonly used in computer serial ports. The standard defines the electrical 
characteristics and timing of signals, the meaning of signals, and the physical size and pinout of 
connectors. The current version of the standard is TIA‐232‐F Interface Between Data Terminal 
Equipment and Data Circuit‐Terminating Equipment Employing Serial Binary Data Interchange, issued in 
1997." From Wikipedia
