I very much doubt it is the fgets function.

I suspect it is the terminal driver. The terminal driver only hands
data back to the application when it sees a newline. It probably only
holds 256 characters.

Try using an editor to create a file with a line longer than 256
characters, and run `test < file', to see whether it is fgets or the
terminal driver.
