to Sets interrupt processing.
Line 150
Line 170 Clears buffer data of the DXY-1000 series
Line 180 Initializes settings for handshake.
Line 190 Sets both monitor mode and hardwire handshake mode to OFF.
Line 200 Taking the delay time until the DXY-1000 series starts outputting as 100
m/sec, sets the output terminator to [CR]CHR$( 13).
Line 230 Taking the ENQ code as [ ENQ]CHR$(5) and the ACK code as
[ACK]CHR$(6), sets the data block to 256 bytes.
Line 1000 Gets out of the main program by interrupt with an ACK signnal from the
to DXY-1000 series. Sets the DATA1 to a 256 byte data block to output them
Line 1120 to the DXY-1000 series.
With the setting of Line 230, the computer sends the [ENQ]CHR$(5) to the DXY-1000
series. Then the DXY-1000 series returns the [ACK]CHR$(6) as an ACK character to the
computer if the remaining buffer capacity is more than 256 bytes.
In this program, the computer checks the plotter's condition in the main program and out­
puts one block (256 byte plotter data) using an interrupt if the buffer still has extra space. If
the buffer has no extra space or no output data in it, the computer processes "Tasks other
than DATA1" .

5.3.5 Handshake Output Specifications

The X on/X off and the ENQ/ACK handshake have different output specifications from each
other, depending on the settings of the device control commands, as shown in Table 5-4
indicates effective output specifications, but "

tions even if they have been set. Also, these output specifications may be affected if they
are output by the RD-GL I output commands.
