Device control instructions
Device control instructions are used to determine the communication sequence between the cutting machine and computer
through RS-232C interface and/or tell the cutting machine the current computer state. among them, some device control
instructions set the output specifications of mode 2 instructions.
Each device control instruction is organized with three letters: ESC (1Bh), “.” and one upper case letter. Device control
instructions are of two types: one with parameters and the other without parameters.
Parameters can be omitted. A semicolon “;” is used as a delimiter to separate parameters if they are input in succession. A
“;” without parameters means that parameters were omitted.
If parameters are omitted, the default value is set. For a device control instruction with parameters, a terminator needs to be
input in order to signify the end of instructions. A colon “:” is used as the terminator which cannot be omitted.

Parallel Interface (in compliance with
specifications of Centronics)
Connector
Instruction Format Parameter Range ([ ] is default) Explanation
Handshake Instructions
ESC .B [ESC].B None Outputs the current remaining buffer capacity.
Output Remaining
Buffer Capacity
ESC .M [ESC].M<P1>;<P2>; P1:Delay time 0—32767(msec) [0(msec)] Sets handshake output specifications.
Set Handshake <P3>;<P4>;<P5>;<P6>: P2:Output trigger character [0(Sets nothing)]
Output P3:Echo terminator [0(Sets nothing)]
Specifications (1)
P4:Output terminator
[
13([CR]
)]
Note:When you specify some values to <P4> and
P5:Output terminator
[0]
<P5>, always set 0 to <P6>. When you specify
P6:Output initiator
[0(Sets
nothing)]
some value to <P6>, always set 0 to <P5>.
ESC .N [ESC].N<P1>;<P2>; P1:Intercharacter delay 0—32767(msec) [0(msec)] Sets an intercharacter delay, and also an Xoff chara-
Set Handshake
<P3>;
•••••;<P11>: P2—P11 [All 0(Sets nothing)] cter for performing the Xon/Xoff handshake. Output :Xoff character (for Xon/Xoff)
Specifications (2) Immediate response character
(for ENQ/ACK)
ESC .H [ESC].H<P1>;<P2>; P1:The number of bytes for 0—15358(byte) [80(byte)] When receiving the ENQ character set by <P2>,
Sets ENQ/ACK
<P3>;
••••••••;<P12>: data block [0(Sets nothing)] compares the value set by <P1> and the remaining Handshake Mode1 P2:ENQ character [All 0(Sets nothing)] buffer capacity, and returns the ACK character to
P3—P12 the host computer when the remaining buffer
:ACK character (only when capacity is larger. The [ESC].H with no parameter
<P2> is set) performs a dummy handshake.
