Some TNCs send square wave for sync instead of HDLC flags ahead of a frame.
The idea is to allow the receiver to recover the data stream and acquire phase
lock more quickly. Sometimes this works, sometimes it messes things up. All
TNCs send at least one HDLC flag, even if they do not use flags for sync idle.
