This command retrieves the framebuffer data used for the display on the
i Series instrument. It is 19200 bytes in size, 2-bits per pixel, 4 pixels per
byte arranged as 320 by 240 characters. The data is sent in RLE encoded
form to save time in transmission. It is sent as a type '5' binary C-Link
response with no checksum.
The RLE encoding consists of a 0 followed by an 8-bit count of
consecutive 0xFF bytes. The following 'c' code will expand the incoming
data.
