signal. Therefore, when using RS-422 and RS485 the software
application must enable the RTS signal.

TIA/EIA-232
RS is the abbreviation for recommended standard. Usually, it is based
on or is identical to other standards, e.g., EIA/TIA-232-F. TIA/EIA-
232, previously known as RS-232 was developed in the 1960’s to
interconnect layers of the interface (ITU–T V.11), but also the pignut of
the appropriate connectors (25-pin D-type or 9-pin DB9S) (ISO 2210)
and the protocol (ISSUED-T V.24). The interface standard specifies
also handshake and control lines in addition to the 2 unidirectional
receive data line (RD) and transmit data line (TD). The control lines
data carrier detect (DCD), data set ready (DSR), request to send (RTS),
clear to send (CTS), data terminal ready (DTR), and the ring indicator
(RI) might be used, but do not necessarily have to be (for example, the
PC-serial-mouse utilizes only RI, TD, RD and GND). Although the
standard supports only low speed data rates and line length of
