Hi Chris,
Yep, you got it working! Looks good. Pink is the echo text, black is the return data text. If you disconnect the DB9 then only one string should show.
With Hercules,
If you hover the mouse over the text fields, you get little help tips. Also, right click on the main text area for more options.
Hex codes are sent in hex format. The hex tick box is to let the program know it is sending hex. It's does not convert decimal to hex. eg: space between chars too: FF D2 A7
You can change how the hex data is returned by the 'special chars' option in the menu. Have a play but not important for the testing.
Cheers,
Damien.
