Im still not clear on the data size.

Ex: Say the number is 11111111, which is 1 byte. After bit stuffing, we get 111111011, which is 8 bytes, 1 byte plus a little more.

So I guess the answer is 11111111, 1-Byte BEFORE
is equal to 11111101 10000000, 2-Bytes AFTER?

Thi s means the data can be any number of bits long, but we've got to keep track of its length, the number of 0s bit stuffed, then add the two together, then round up to the nearest Byte, and THATS the number of size of the data?

If thats so, then WHOA! Lets put some restrictions on the information type! Because I can rig up the transmitter for 1 byte data length, but it would be a nightmare to change it for any size!

Later,
Jim
