<CR/LF> or <CR> or <LF>?

You need to read some more about HID. Keypads send keypresses, not text. You probably need do nothing more than send the code for the Enter key to have the text come out correctly on all systems.

Wow, never thought "they" would have a code for the Enter key.

Thanks, a bit more reading to do!

We keep on learning :-) :-).

Although strictly, the "Enter" key on keyboards (the popular ones; not many alternative nowadays, I imagine) does have its own code: $5A press, $F0 $5a release... (practically 0% relevant to your query, that is :-).

That depends on what software on the wintel/linux whatever side will take your data. If it is a terminal emulation - just prints out what you send in a window, as you seem to want - then CRLF is probably the most universal. But there are terminals which do autoLF on CR etc., generally a thing one can switch on or off as wanted.

Unless it's the keypad enter key. Then it's E0 5A for press and E0 F0

And if we're talking about USB HID, the enter key is 0x28, and the keypad enter key is 0x58. USB HID doesn't have release (break) codes the way the PS/2 keyboard does: It's down, or it's not.

Dave, would you please post some info (link etc.) on that USB keyboard thing? I have yet to look into it and do it so I have not done any searches, but I may have to before I know so having the right file or bookmark would be helpful.

Thanks,

Many thanks for the pointer,
