Among the features of RS232 serial cable, one male end and one female end, the following can be mentioned:
Special RS-232 cable for updating through software for electronic components
Especially for use in GSM, industrial modems with serial port, PLC devices, monitoring devices, etc.
The standard serial port was one of the most common external computer connections until the last few years and has the ability to connect various devices such as modems, scanners, printers, etc. But due to the need for higher speeds in the current application, nowadays other ports are being replaced by this port. For example, the parallel port can send 8 communication lines simultaneously.
Or the ports that have the ability to send data extremely fast, are suitable alternatives (such as USB and 2 USB) of the new serial for this port. However, the use of this port is not only not obsolete yet, but sometimes due to economic and technical reasons, the use of this port is more preferable than other ports.
