RS-232 - Wikipedia
2 weeks ago - It formally defines signals connecting between a DTE (data terminal equipment) such as a computer terminal or PC, and a DCE (data circuit-terminating equipment or data communication equipment), such as a modem. 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.

r/embedded on Reddit: RS232 serial communication two-way - best practice
December 7, 2024 -
I’ve got an Arduino setup with a max3232 allowing me to send and receive serial commands between my arduino and old AV equipment I have.
At the moment I send with the arduino and then essentially ‘listen’ in a loop for a response. My question is ‘what is best practice for doing this?’. I want to maximise the chance of the AV equipment ‘seeing’ the command come through, and then want to maximise the chance of my arduino ‘hearing’ the response and capturing it.
As I understand it, there’s no acknowledgements that happen in the communication in either direction, and the arduino can’t listen and speak at the same time. So what’s the best practice to minimise the chance of the arduino picking up a response?
Thanks!
