Calculate CRC-16/KERMIT
Calculate CRC-16/KERMIT from text. KERMIT uses the 0x1021 polynomial with reflected input and output.
Reflection is the important difference from CRC-16/XMODEM. The same text gives different values under the two profiles.
Output width
CRC-16/KERMIT produces a 16-bit result. The calculator pads the hexadecimal output to 4 characters so leading zeroes are visible.
