Create a (log) file ON THE HOST COMPUTER of the output from the serial port

Hi,
The serial port is WONDERFUL!
The only feature missing is the option to be able to save the output of the serial port onto the host computer as a file.
Some terminal emulators allow this feature.
Please add it to PythonEditor.
Thank you!

從 PythonEditor 開始，定位串列埠輸出處理部分；issue 未指定任何檔案、測試或進入點。確定目前如何顯示輸出，以及預期的主機檔案行為為何。完成的標準是：串列輸出可以在主機電腦上儲存為檔案，且該行為已獲得驗證。

由索引模型根據 Issue 內容生成。
