Explanation
Outputs the current remaining buffer
capacity.
Sets handshake output specifications.
Note: When you specify some
values to <P4> and <P5>, always
set 0 to <P6>. When you specify some
value to <P6>, always set 0 to <P5>.
Sets an intercharacter delay, and also
an Xoff character for performing the
Xon/Xoff handshake.
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.
{0}
Sets the type of handshake used.
The types of handshakes corresponding
to the parameters 0 to 3 and the setting
combinations of their equivalent device
control instructions are as follows:
