ASCII extension

noxos extends ascii to support special characters and commands. The extension uses byte blocks in the following form:

+----------+----------------+-------------------------------+-----------+
| SHIFT IN | Length of Data | Data                          | SHIFT OUT |
| 1 byte   | 2 bytes        | +---------+-----------------+ | 1 byte    |
| 0x0F     |                | | Command | Additional Data | | 0x0E      |
|          |                | +---------+-----------------+ |           |
+----------+----------------+-------------------------------+-----------+
