6-14 Escape Sequences
Example: the command ESC.N;19: establishes an Xoff Trigger String consisting of the
ASCII DC3 character (character code 19, also known as XOFF). This character is sent when
the buffer is nearly full, at a threshold established by the
ESC.H or ESC.I command. There
is no intercharacter delay, since the first parameter was defaulted to zero by the semicolon.
Example: the command
ESC.N10;19: establishes an Intercharacter Delay of approximately
10 milliseconds, or 0.01 second. This might prove useful if the host computer is unable to
accept Automove transmissions at whatever speed happens to result from the current baud
rate setting. Many small-computer BASIC interpreters fall into this category. The second
parameter, 19, sets up the same DC3 Xoff Trigger String as in the above example.
ESC.O Output Extended Status
This command causes the Automove System to output an Extended Status code. This will
be a decimal value whose bits have the following meanings:
Table 24 - Extended Status Code Definitions
Bit Dec. Value Meaning if 1
0 1 The machine is executing a Download Sequence.
1 2 Not used, value undefined.
2 4 The STOP button or external Emergency Stop switch is currently
actuated. The CS and "ESC.!2:" commands are ignored while this
bit is set, unless the FP command disables STOP. This bit is
cleared when the Stop switch is released.
(See also bit 6, below).
3 8 The input buffer is empty.
4 16 The machine is in the Paused state.
5 32 The machine is in the Motor Slipped state; i.e., the optional Step
Verify circuit has detected a motor slip. This bit is cleared by the
CS command or by "
ESC.!2:".
6 64 The machine is in the Emergency Stopped state. This bit is
cleared by the CS command or by "ESC.!2:".
7 128 The non-volatile memory has failed its internal consistency check.
This bit may be set after reset or power up. It is cleared by
"
ESC.!5:", "ESC.!6:", "ESC.!7:", or "ESC.!8:". See Appendix A.
