Explanation
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

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
10-15358 (byte) [80 (byte)]
Used for performing the Xon/Xoff handshake and
Set Xon/Xoff
<P3> ; •••••••• ;<P12>:

the ENQ/ACK handshake mode 2.
Handshake and
The number of data block bytes
The [ESC].I instruction with no parameter performs
ENQ/ACK
(for ENQ/ACK (mode2))
a dummy handshake. In a dummy handshake,
Handshake Mode2
P2: ENQ character
[0 (Sets nothing)]
always returns the ACK character to the host
(for ENQ/ACK (mode2))
computer, regardless of the remaining buffer
0 (for Xon/Xoff)
capacity, when receiving the ENQ character.

ESC .@
[ESC].@ P1;P2:
P1: Ignored
Controls the DTR signal (No. 20 pin of RS-232C).
Controls DTR
P2: DTR signal control
0-255 [1]
An even number parameter (e.g. 0) always sets the
DTR signal to High without performing the
hardware handshake. An odd number parameter
(e.g. 1) performs the hardware handshake and
controls the DTR signal according to the remaining
buffer capacity.
