Device Control C O M M A N D; Handshake Mode Commands - Roland DXY-1300 Command Reference Manual

5,4 Device Control Commands
The device control command is used to determine the communication protocol between a com
puter with an RS-232C interface and the DXY-1000 series and let the computer know the cur
rent status of the DXY-1000 series. There are also device control commands to set the specifica
tions for output by RD-GL I commands.
The device control command consists of three characters, such as [ESC]CHR$(27), " ." , the last
of which is a capital letter or a symbol. And it is divided into two kinds: one with parameters and
one without parameters.
Parameters may be omitted. A semicolon " ; "
A semicolon without parameters indicates that parameters are omitted. For the device con­
trol command with parameters, you are required to key in terminator at the end of an instruction
sentence. A colon " : "

5.4.1 Handshake Mode Commands

E S C .B
FORMAT
[ESC] .B
EXPLANATION
This command tells the DXY-1000 series to output the current remaining buffer capacity
to the computer. Since the computer knows the remaining buffer capacity with this com­
mand, it can output data below this capacity to the DXY- 1000 series. Therefore, using
this command allows you to prevent the buffer from an overflow. See " Example" of
" 5.3.2 Software Checking Handshake" .
E S C .M
FORMAT
[ESC] .M P1;P2;P3;P4;P5;P6:
EXPLANATION
This command sets the output specifications for handshaking.
P1:
When the computer asks the DXY-1000 series to output, the parameter P1 sets
the delay lime until the DXY-1000 series starts outputting. The parameter range is
from 0 to 66535. The unit is m /sec. A decimal parameter will cause an error.
(Default value: 0)
EXAMPLE: P R I N T # 1 , CHR$( 2 7 ) ; " , Ml 0 0 : " ;
This command sets an approximately 100m/sec delay time.
is used for the terminator and this cannot be omitted.
Remaining buffer capacity output
Set handshake output specification (1)
is used on a delimiter to separate parameters.
