How to configure SmartSDR for Win to work with external keyer attached to COM port?

dankeboo Member ✭✭

I have NANO Keyer MK2. My PC recognized CH340 and CH340K as COM7 and COM6 but I am not sure how SmartSDR for Win to be connected to these COM ports so that it will work with the external keyer. Any help appreciated.

    Does the Nano Keyer use the CTS or DTR signal of the COM port to trigger PTT?

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
