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.
ESC .I
[ESC].I<P1>;<P2>;
P1:Limit of the remaining
0-15358(byte) [80(byte)]
Used for performing the Xon/Xoff handshake and
Set Xon/Xoff
<P3> ;••••••••;<P12>:
buffer capacity (for Xon/Xoff)
the ENQ/ACK handshake mode 2.
Handshake and
The number of data block bytes
The [ESC].I instruction with no parameter per-
ENQ/ACK Hand-
(for ENQ/ACK (mode2))
forms a dummy handshake. In a dummy hand-
shak Mode2
P2:ENQ character
[0(Sets nothing)]
shake, always returns the ACK character to the
(for ENQ/ACK (mode2))
host computer, regardless of the remaining buffer
0(for Xon/Xoff)
capacity, when receiving the ENQ character.

The types of handshakes corresponding to the para-
meters 0 to 3 and the setting combinations of their
equivalent device control instructions are as follows:
Status Instructions
ESC .A
[ESC].A:
None
When receiving this instruction, returns the follow-
Output Model Name
ing numerals to the host computer.
1350 (DXY-1350A) 1150 (DXY-1150A)
ESC .O
[ESC].O:
None
Outputs the decimal value that represents the status
Output Status Word
of a plotter. This value is the sum of bits shown in
the table below.
