ASCII string CR insert

Dear community,

I am trying to connect to a device with UCON;
I can communicate with the device with ASCII strings over a terminal;
unfortunately it doesnt work if I enter my ASCII string in Kepware.

The device only recognizes ASCII strings; if I copy my ASCII string from a converter with the CR and LF into the terminal it works and responds.

If I try to insert the string into Kepware's Interface it doesnt work.
Manully inputing the string and entering  ALT+13 for CR and ALT+10 for LF also doesnt work.
The device doesnt answer to the string.

How else can I enter CR and LF into the interface? 

I can't seem to find anything about it on the net or help.

Thanks in advance.
