I understand nothing what you wrote but as I am an obedient child I do what the aparatus' user's manual says.

I spent the whole day to find out when the manual says; 0x1b 0x2e in the senddata method shoud be 0x1b+0x2e (without ") and worse. It only works well if I put "chr(27)+chr(n)"

Why if you need chr(27) you put in the manual "0x1b"? Apparently you look more important if you use hexa notation.

If I understand something what you wrote I must expect my nice aparatus will blow up...

If so you might tell me "I told you..."

Thank you.
