Ymodem is an error-correcting, block-oriented protocol. Ymodem transfers start with a header block containing file name and date-time stamp for the file, followed by the contents of the file. This continues for as many files as the sender transmits. To use this protocol, you must configure the COM port to use 8-data bits. By default, Ymodem uses the 16-bit CRC block check method.
The configuration settings for this protocol in the FileLink Configurator appear below. Click on a particular setting control for more information.
