InhEolWrp (C)
Factory default: Unchecked
The Inhibit End of line Wrap option determines whether characters wrap to the next line when
the right margin is reached. When checked (i.e. inhibited), on reaching the right margin, the last
character position will be overwritten with every new character received until a carriage return or
other cursor movement command is issued.
●
Line/Page (D)
Factory default: Unchecked
The setting of this option determines whether data is sent a line or a page at a time when in Edit
mode.
When this option is checked, data will be transmitted a line at a time.
When unchecked, data will be transmitted a page at a time. Page data will either be from the
beginning of display memory or from the current cursor position.
●
InhHndShk (G) InhDC2 (H)
Factory default: Unchecked
The combined setting of these two options determine the type of handshaking used when blocks of
data are transmitted to the host.
One of three types of handshake may be used:
◦
No handshake. Blocks of data are sent immediately when the relevant transmit key is
pressed.
◦
DC1 handshake. Data is only sent to the host when the host sends an ASCII DC1 control
code to request it.
◦
DC1/DC2/DC1 handshake. The host sends an ASCII DC1 control 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
