b3270 screen-mode Indication

### screen-mode Indication

Indicates the screen dimensions and characteristics. This is reported at initialization time, and any time these parameters change (which can only happen when disconnected).

Attribute | Always present? | Purpose
--- | --- | ---
model | yes | Model number (2, 3, 4 or 5)
rows | yes | Number of rows
cols | yes | Number of columns
color | yes | true or false
oversize | yes | true or false
extended | yes | Extended data stream: true or false

If color is true, the emulator will report the screen contents with specific colors. If color is false, the screen will be reported without color information.

If oversize is true, the screen dimensions are larger than the default for that model number.

Example:

    <screen-mode model="2" rows="24" cols="80" color="true" oversize="false"/>
