Text file, < 2k bytes, all printable characters, linefeeds, and returns. No blank lines.
I need to be able to offer the user the ability to download a configuration file to a device, without confusing the user and with reasonable reliability.
I'm thinking I'll just tack a line onto it that starts with some "impossible" characters, then a checksum to end. Then I'll provide that to the user as an ASCII file to download.
Thoughts?
