Kermit supports three kinds of error checking: single-byte checksum, double-byte checksum, and three-byte CRC. During file transfers, Reflection uses the specified level of error checking, unless the Kermit program at the other end of the transfer does not support that level. In that case, Reflection uses the highest level that the remote system supports. CRC is the highest level of error checking and the most thorough. Single-byte checksum is the lowest level, but is the fastest.
Kermit uses single-byte checksum.
Kermit uses double-byte checksum.
Kermit uses three-byte CRC checksum. (The default.)
