Setup Menus LineTx (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: 1 No handshake. Blocks of data are sent immediately when the relevant transmit key is pressed. 2 DC1 handshake. Data is only sent to the host when the host sends an ASCII DC1 control code to request it. 3 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. HP 700-92/96 Settings 147

LineTx (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:
1
No handshake. Blocks of data are sent immediately when the
relevant transmit key is pressed.
2
DC1 handshake. Data is only sent to the host when the host
sends an ASCII
DC1
control code to request it.
3
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.
