XMODEM
In this protocol, the image file is transmitted in blocks of 128 bytes. The protocol includes error
detection information (CRC or checksum). All blocks must be acknowledged by the host, and if
an error is detected, the host will request the block again.
XMODEM-1K
In this protocol, the image file is transmitted in blocks of 1K bytes. The protocol includes error
detection information (CRC or checksum). All blocks must be acknowledged by the host, and if
an error is detected, the host will request the block again.
YMODEM/YMODEM-G
This is a double mode protocol and is used to send multiple files in batch mode. The host
instructs MICRImage whether to use YMODEM or YMODEM-G. In the YMODEM protocol,
the image file is sent in blocks of 1K bytes, and all blocks must be acknowledged by the host. In
the YMODEM-G protocol, the image files are also sent in blocks of 1K bytes, but the blocks are
not acknowledged by the host.
BINARY
In this protocol, the image file is transmitted as binary data but no length is provided. The IS
(Image Size) command can be used to query for the size of the image file.
