WR Streamers hang if 0xCAFE is the last word
0xCAFE is a special character in streamers. if this sequence is sent, streamers add empty word (0x0000). This works fine except when 0xCAFE is the last word (of block and/or frame). In this case, the tx streamer hangs. Until this is fixed, do not send 0xCAFE as the last word. Consider sending empty word as last to ensure streamers do not hang.
