h1. RS232 vs ITU-T V.24 Signal Names There are unfortunately a lot of different terms/names used for serial interfaces, depending on which context/spec you are looking at. This table provides a mapping of the most common signals between different specs: |_.Common Name|_.RS232|_.ITU-T V.24|_.Description| |GND|AB|102|Signal/System Ground| |TXD|BA|103|Received data| |RXD|BB|104|Transmitted data| |RTS|CA|105|Request to Send| |CTS|CB|106|Claer to Send| |DSR|CC|107|Data Set Ready| |DTR|CD|108/2|Data Terminal Ready| |CD|CF|109|Carrier detect| |-|-|113|Transmitter signal element timing (DTE source)| |-|-|114|Transmitter signal element timing (DCE source)| |-|-|115|Receiver signal element timing (DCE source)| |RI|CE|125|Ring Indicator| |-|-|133|Ready for receiving| h2.
