Why can't I send more than 512 bytes using the STXT instruction?

FAQ #101468

 

Symptom
When sending a text with a length of more than 512 bytes on a PCD3 or a PCD2.M5 with a firmware older than 1.14.23 the text which is sent is not correct.
In case the text to be sent contains sub-texts which are introduced using interpreted text (e.g. the $Lnnnn) and the final length to be sent is more than 512 bytes, the same phenomenon can be observed.

Solution
Please update the firmware of your PCD to version 1.14.23 or later.
