Serial Communication in Canonical Mode [closed]
Clash Royale CLAN TAG#URR8PPP
I am sending commands over a serial port from a Linux embedded device to some serial enabled firmware using ascii human-readable commands terminated by newlines. Is it appropriate to use canonical mode here, or is canonical mode usually reserved for interactive terminals? The examples I find online for this type of application use raw mode.
In particular, in canonical mode, how do I check without blocking if an entire line is available for reading?

what language or event framework are you using? with async I/O there's usually "hey there's some data available" notifications or callbacks

I'm using C/C++. Since I don't want to parse lines myself, I want to know if a full line is available, not just some data. There is a discussion happening under my post on Stack Overflow: stackoverflow.com/questions/53728798/…

what language or event framework are you using? with async I/O there's usually "hey there's some data available" notifications or callbacks
