I'm not sure I really understand the question...

There isn't anything built in to Espruino that separates specific commands in the output stream - it is just a sequence of characters (as would go to a VT100 terminal app).

You may be seeing char code 8 which is a delete, because normally the console outputs > as a prompt, but to print something it must first delete that, write the text, and then re-add it.

To avoid that you can run echo(0) which will turn off the console echoing back what you write (and the > prompt). When you type in the IDE the device will appear to be unresponsive, but it will still output the text you send it

I just wanted to say that when I catch console logs and answers from interactive console with code like this
```
USB.on('data', data => {
  inbuf.Push(data);
});

setTimeout(() => {E.setConsole(LoopbackA);}, 200);

LoopbackB.on('data', data => {
  outLogs.push(data);
  USB.write(data);
});

setTimeout(() => {
  console.log('some text');
}, 500);

setTimeout(() => {
  LoopbackB.write('2+3\r');
}, 1500);
```
I get logs like this:
```
[
  "<- USB\r\n>",
  "\r\x1B[Jsome text\r\n>",
  "2+3\r\n=5\r\n>",
  "10+3\r\n=13\r\n>",
  "\r\x1B[J-> USB\r\n"
 ]
```
That looks quite readable, but some situations lead to logs like this:
```
"outLogs\r\n=[ \r\n  \"" ... "\\n ]\\r\\n>\"\r\n ]\r\n>"
```
So I have to remove all special symbols somehow. Yeah, it's not hard at all to write a simple parser on regexps for those exact types of logs, but as I don't know how exactly IDE is formatting logs, I may easily trap into using code that doesnt work correctly for some cases. So, what would you advice?
