([ ] is default) Explanation
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 per-
forms a dummy handshake. In a dummy hand-
shake, 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 para-
meters 0 to 3 and the setting combinations of their
equivalent device control instructions are as follows:
