I just type or paste it in miniterm and hit return. Miniterm sends the return as CR, but it also works with CRLF.

This is the response from the device, saying that my command was ok, and it also does what it should (it's an hdmi 4-4 matrix, it switches the first output to the next input).

In my app, that doesn't make any difference, never works. In miniterm, only CR and CRLF work, LF alone does not.

This evening I'll try with com0com to see what is really sent...
