P - Protocol
Used for shipping an image. Protocol covers two features of the image data being
sent to the host. It addresses the protocol used to send the data (Hmodem, which
is an Xmodem 1K variant that has additional header information), and the format
of the image data that is sent.
S - Pixel Ship
Pixel Ship sizes an image in proportion to its original size. It decimates the image
by shipping only certain, regularly spaced pixels.
Example: 4S would transmit every fourth pixel from every fourth line.
The smaller number of pixels shipped, the smaller the image, however, after a
certain point the image becomes unusable.
