Hello - I have the following problem with this codes: very often, if the first key in a sequence is the digit "2", the receiver doesn't accept it. To circumvent this situation, I have found that if I send a "3" before the first "2" then the latter key (and any following "2") is received correctly. Thus, in order to send, say, the sequence "2 2 7", I send "3 ESC 2 2 7". Isn't it a bit weird?
