* 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

* tty interface. The protocol can support other systems as well, but might
