Some necessary calculations.

Assuming 3 numeric text characters per data value e.g. "362" + a CR/LF pair:

1. Time taken to scroll data across the screen-width:

MP2k:in landscape mode there are 427 pixels so the time is
((5 ASCII characters * 10 bits / 1200 bps) + 80mS delay per sample) * 427
= ((50/1200) + 0.08) * 427 = 52 seconds
OMP/MP100:((50/1200) + 300mS delay per sample) * 233 pixels = 79 seconds.
