> if I'm correct to apply here such formulae
Whether serial transmission is as simple as start:data:parity:stop repeated, or
not, I still have no idea. But I'm posting again to say in those calculations
I was off a whole order of magnitude, sorry.
I imagine the calculator I used reported "0.004583333333333333", which I then
misread to get that silly answer. After all, just 800 bit/s = 100 byte/s = 10
ms/ byte. Scaling 3X says 2400 bit/s = 3.3 ms/ data byte. Which suggests 2400
* 8/11 bit/s is 1745 data bit/s is 4.58 ms/byte ... NOT 45.8 ms/byte.
Saving 3 bytes per packet therefore saves just 13.75ms.
Maybe still worthwhile, but no longer so very wonderful.
