FAQ:
Q: What is the use of DTR pin in serial RS232?
A: Data Terminal Ready (DTR) is a control signal in RS-232 serial communications, transmitted from data terminal equipment (DTE), such as a computer, to data communications equipment (DCE), for example a modem, to indicate that the terminal is ready for communications and the modem may initiate a communications channel.
Q: What is RS232 protocol and how it works?
A: RS232 is a serial information transfer protocol standard that defines both the protocol (method of transmission of data) and the physical hardware to do it. This document describes how it works at the physical level so you will know what signals you can expect to see at the microcontroller pins.
Q: How does RS232 work?
A: RS232 works using two-way communication. A request to send, or RTS, is initiated from the host device. The answering device then clears the way for the information and sends a CTS, or clear to send. The data is then transmitted. It’s clean and simple, if limited. RS232 is great for applications that need simple, straightforward data transference.
Q: What is a RS232 sniffer?
A: An RS232 Sniffer is an essential tool for businesses of all sizes with products that use RS232 Communications, and perhaps it’s easy to understand why. This solution passively monitors full duplex communication, which provides powerful diagnostic capabilities without affecting the system under test.
