help to print CODE128 (CODE C) using ESC / POS

I use the function below to print code128 but I'm not getting it to work.

ESC / POS scope G S k m n d1 ... dk

.so it does not work

Socket.SendData(TEncoding.UTF8.GetBytes(
chr(29) + chr(107) +      //GS k
hr(73) +                 // m
Chr(Length('4318093080969600016265001000000040102256116')) +    // n
'4318093080969600016265001000000040102256116'));

. so it works

Socket.SendData(TEncoding.UTF8.GetBytes(
chr(29) + chr(107) +      //GS k
hr(73) +                 // m
Chr(Length('43180930809696')) +    // n
'43180930809696'));

code128 supports2≤n≤ 255 but is not accepting 44. Anyone with similar problem or solution for this ??
