I don’t know if you’re on a PC, but Ctrl- left arrow and Ctrl-right arrow are my friends. Add a shift in there and things get REALLY interesting.
ASCII 22 is the character that indicates synchronism can be achieved.
Here is the data-communication definition of synchronism.
synchronism: 1. The state of being synchronous. 2. For repetitive events with the same, multiple, or submultiple repetition rates, a relationship among the events such that a significant instant of one event bears a fixed time relationship to a corresponding instant in another event. Note: Synchronism is maintained when there is a fixed, i.e. , constant, phase relationship among the group of repetitive events. 3. The simultaneous occurrence of two or more events at the same instant on the same coordinated time scale. (188)
synchronous transmission: Digital transmission in which the time interval between any two similar significant instants in the overall bit stream is always an integral number of unit intervals. (188) Note: “Isochronous“ and “anisochronous“ are characteristics, while “synchronous“ and “asynchronous” pertain to relationships.
So: a “synchronous idle” is a metronome.
.. or the old spy movies, “Everybody synchronize your watches”. [send SYN, receive SYN, means clocks are synchronized] now begin data transmission. ASCII 22.
