#144573 - my quick test is: Responding to: ???'s previous message |
Dear 5678,
Welcome to 8052.com. ... after successful autobauding (UUUU), I type in the following (I do it so often I even don't need to count the zeros or think about the checksum): :020000050000F9 and the echo should look like: :020000050000F9BF. If not, it's some user program which dumbly echoes what's typed in; or, worse, the terminal program has turned local echo on and there was no successful autobaud. Please come back with your results.
