#183509 - how to use bit 9 for data bytes? Responding to: ???'s previous message |
bit 9 is what distingguishes data bytes from "control" bytes:
bit 9 SET identifies a byte as a "control" byte; bit 9 CLEAR identifies a byte as a data byte. Erik's suggestion was that you have a "control" byte at both the start and the end of a message: http://www.8052.com/forum/read/183505 |

re: 1 byte - MDB | 01/01/70 00:00 | |
Strong work | 01/01/70 00:00 | |
Just as there is a timeout | 01/01/70 00:00 | |
my reason | 01/01/70 00:00 | |
Protocol should preferably support dry-counting for EOP pos | 01/01/70 00:00 | |
Methods in brief | 01/01/70 00:00 | |
At least 1 packet less (sic) | 01/01/70 00:00 | |
