How to eliminate extraneous characters from Console/print on the USB port?

I would like to act on the output from the Espruino by listening to the Espruino's port on node-red.

I am getting 7 leading bytes for a one-byte payload ('1') i.e. (decimal) 62,13,27,91,74,21,16,49,13,10.

Same result for print("1") as for console.log("1").

Is this because the console is 'Telnet' (from process.env.CONSOLE)?

Is it possible to eliminate the leading chars?

Thanks.
