 === Description
-`readBytesUntil()` reads characters from a stream into a buffer. The function terminates if the terminator character is detected, the determined length has been read, or it times out (see link:../streamsettimeout[setTimeout()]).
+`readBytesUntil()` reads characters from a stream into a buffer. The function terminates if the terminator character is detected, the determined length has been read, or it times out (see link:../streamsettimeout[setTimeout()]). The function returns the characters up to the last character before the supplied terminator. The terminator itself is not returned in the buffer.
 
 `readBytesUntil()` returns the number of bytes placed in the buffer. A 0 means no valid data was found.
