Graphic Input (Gin); Gin Data - AT&T 730 MTG User Manual

Graphic Input (GIN)
The Graphic Input feature of the 4014 allows you to send the current
cursor or drawing position to the host when your application asks for
it. The GIN Request command coming from the host causes the
terminal to send position information depending on which mode
(Alpha Mode, Graph Mode, or GIN Mode) the terminal is in. Position
information is sent as the GIN Address in a GIN Data format.
GIN Data
For Alpha and Graph modes, GIN Data consists of the Terminal Status
Byte, the GIN Address of position (see this section), and the GIN
Terminator, sent in that order. For GIN Mode, GIN Data consists of the
GIN Address of the crosshair cursor followed by the GIN Terminator.
Bypass Condition
After GIN Data is sent, the Bypass Condition goes into effect. The
Bypass Condition prevents GIN Data from being recognized by the
4014 emulator when it is echoed back from the host. Bypass is also
active when the Communication option on the Options submenu of the
4014 GS menu is set to
local.
Bypass can also be activated with the
Bypass Condition command,
ESC
CAN.
Bypass must be cleared before host communications can resume. To
do so, you can either set the GIN Terminator to be
a CR
(carriage
return), press the Carriage Return, or send the
US
command to the
terminal from the host.
