  41  * SSH1:
  42  * The tty mode description is a stream of bytes.  The stream consists of
  43  * opcode-arguments pairs.  It is terminated by opcode TTY_OP_END (0).
  44  * Opcodes 1-127 have one-byte arguments.  Opcodes 128-159 have integer
  45  * arguments.  Opcodes 160-255 are not yet defined, and cause parsing to
  46  * stop (they should only be used after any other data).
  47  *
  48  * SSH2:
  49  * Differences between SSH1 and SSH2 terminal mode encoding include:
  50  * 1. Encoded terminal modes are represented as a string, and a stream
  51  *    of bytes within that string.
  52  * 2. Opcode arguments are uint32 (1-159); 160-255 remain undefined.
  53  * 3. The values for TTY_OP_ISPEED and TTY_OP_OSPEED are different;
  54  *    128 and 129 vs. 192 and 193 respectively.
  55  *
  56  * The client puts in the stream any modes it knows about, and the
  57  * server ignores any modes it does not know about.  This allows some degree
  58  * of machine-independence, at least between systems that use a posix-like
  59  * tty interface.  The protocol can support other systems as well, but might
  60  * require reimplementing as mode names would likely be different.
