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

: Huh?

OK, what I meant is:

1.) How big can the data your trying to send be? For example if the data you want to send is 11111111 (1-BYTE), then what is the format of this specific data when it comes out as packets? For example, from what Ive heard I take it to mean :

HEADER-11111101-CRC-Se0-HEADER-10000000-CRC-Se0

Thus 1-BYTE was actually sent out as 2-BYTEs due to bit-stuffing. 2 packets are needed to transmit even though 1 BYTE is the size of teh original data. And yes, I intenitalliy left out data_length copies.

Hope this helps
