DC1/DC2/DC1 handshake. The host sends an ASCII DC1 con-
trol code, to which TeemTalk replies by sending a DC2 code if
ready to transmit. The host sends the DC1 code again to cause
the data block to be transmitted.
The type of handshake used for block transfers is determined by the
type of block transfer to be performed, the mode that the HP70092
emulation currently operating in (character, block line, block page,
or modify mode), and the setting of these two options.
The setting of these two options will have the following general
effect:
InhHndShk
only selected:
The DC1/DC2/DC1 handshake or no handshake
will be used.
InhDC2
only selected:
The DC1 handshake or no handshake will be used.
InhHndShk
and
InhDC2
selected:
No handshake will be used.
Enq/ack pacing
Factory default: Checked
The setting of this option determines whether the Hewlett Packard
ENQ ACK handshake is used.
When checked, the host can send an ASCII ENQ (enquiry) control
code at the end of transmission asking if the data has been processed,
to which TeemTalk will reply by sending an
ACK (acknowledge)
code when it has. Note that this form of handshaking has the lowest
priority after hardware and
XON/XOFF handshaking.
EscXfer
Factory default: Unchecked
This option determines whether escape sequences relating to the dis-
play are sent when the display memory is transferred to the printer.
