B.44 WRITEFILE Create/Append Files on CF Card

The writefile command allows you to create files on the CF card or append data to an existing file on the CF card.

The writefile command writes data to a file named filename on the CF card. If a file named filename does not exist, the file is created. If a file named filename already exists, data is appended to the end of the file. Only simple filenames (maximum 8 characters and an optional 3-character extension) are supported. data is up to 1024 bytes, and is ASCII data if the writefile command is issued in ASCII but can be binary in a binary writefile message.

length specifies the number of bytes supplied as data.
