Parameter Range
P1: The number of bytes for 0-15358 (byte) [80 (byte)]
data block [0 (Sets nothing)]
P2: ENQ character [All 0 (Sets nothing)]
P3-P12
: ACK character (only when
<P2> is set)
P1: Limit of the remaining 10-15358 (byte) [80 (byte)]
buffer capacity (for Xon/Xoff)
The number of data block bytes
(for ENQ/ACK (mode2))
P2: ENQ character [0 (Sets nothing)]
(for ENQ/ACK (mode2))
0 (for Xon/Xoff)
P3-P12 [All 0 (Sets nothing)]
: Xon character(for Xon/Xoff)
ACK character
(for ENQ/ACK (mode2))
P1: Ignored
P2: DTR signal control 0-255

([ ] is default)
When receiving the ENQ character set by <P2>,
compares the value set by <P1> and the remaining
buffer capacity, and returns the ACK character to
the host computer when the remaining buffer
capacity is larger. The [ESC].H with no parameter
performs a dummy handshake.
Used for performing the Xon/Xoff handshake and
the ENQ/ACK handshake mode 2.
The [ESC].I instruction with no parameter performs
a dummy handshake. In a dummy handshake,
always returns the ACK character to the host
computer, regardless of the remaining buffer
capacity, when receiving the ENQ character.
Controls the DTR signal (No. 20 pin of RS-232C).
[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.
