Serial port line break only at \r\n (Read 9189 times)

	Hi again =) I've come to pester some more. I noticed that the new shiny serial port monitor only breaks lines when it receives a \r\n (Windows). All of my debug code uses only a trailing \n (*nix). It would be very cool if there was an option in the settings that would auto replace the line endings when enabled. Something like, ConvertSerialEOL ? On receive -> if char = \n, append \r\n. Congrats on the new 10.x extension btw, it's a lot more sexy. -- bbf

	Thanks:) That makes sense Should it be a system wide setting for all the serial windows or a setting per window?

	actually another question how do arduino and other serial tools handle this. does \n wrap text lines? if so we should do this by default?

	You are right, it might make sense to have it per serial windows... maybe a little checkbox at the bottom. In arduino, the serial monitor is just a wrapper for the RXTX library. And there, a simple \n will the cursor skip to the next line. I was mostly using that, and it was one of the reasons I saw the clutter when using your serial window. But the arduino library has a Serial.println() which sends a \r\n. Since some people will be using that, it makes sense to have it configurable. In my own serial parsing library, implemented in C for the arduino itself, I have an auto-magic way of handling these sequences. I convert all \r\n to \n by reading, and peeking the next char.

	funny, in vs if the option is on, i was thinking of find the previous char to \n and if not \r then replacing \n with \r\n we've been watching the cpu usage with serial windows open and ensured the serial stuff is quite efficient. this option would slow things down a fraction because at the moment incoming serial data is not scanned or retained except in the viewer textbox. Let's see if it does slow things down, if not then maybe it could be a global option? Would you mind adding it as a request to the issue tracker on codeplex. I think it's fair to say that it is an issue because we should be doing everything that arduino does thanks
