+ * SSH1:
+ * The tty mode description is a stream of bytes.  The stream consists of
  * opcode-arguments pairs.  It is terminated by opcode TTY_OP_END (0).
  * Opcodes 1-127 have one-byte arguments.  Opcodes 128-159 have integer
  * arguments.  Opcodes 160-255 are not yet defined, and cause parsing to
  * stop (they should only be used after any other data).
  *
+ * SSH2:
+ * Differences between SSH1 and SSH2 terminal mode encoding include:
+ * 1. Encoded terminal modes are represented as a string, and a stream
+ *    of bytes within that string.
+ * 2. Opcode arguments are uint32 (1-159); 160-255 remain undefined.
+ * 3. The values for TTY_OP_ISPEED and TTY_OP_OSPEED are different;
+ *    128 and 129 vs. 192 and 193 respectively.
+ *
  * The client puts in the stream any modes it knows about, and the
  * server ignores any modes it does not know about.  This allows some degree
  * of machine-independence, at least between systems that use a posix-like
