- It does.
- (Both guard time and escape character can be configured by S register.)

- You mean
- - no data for <guard time>
- - three instances of the <escape character> with pauses shorter than
- <guard time> in between
- - no data for <guard time>
-
- In the somewhat unlikely case of this accidentally happening the modem
- will drop into command mode.

-
- It would mean that the modems would have to wait for a multiple of
- <guard time> before transmitting the data. Very bad idea.
-
- If you are uncomfortable with the escape sequence, go ahead and disable
- it. Setting the escape character to 128 or above will do this.
