Intermec Terminal Emulator (ITE) Programmer’s Reference Manual
These are the input and output commands and hex codes with additional reference
information about each command.
Input Commands
Input commands consist of immediate and AID-associated Read commands.
Immediate commands are executed when the controller receives the command. AID-
associated commands are queued until the operator presses an AID-generating key
such as Enter/Rec Adv. Other AID-generating keys are listed in the chapter for each
computer.
Read Immediate
Description:
The Read Immediate command sends back the contents of all the input fields on
the display. This command is similar to the Read Screen command, except the data
comes from the format table rather than the display.
Restrictions:
This command must be the last command in the chain and the controller must have
change of direction (CD). The command is rejected if the computer is in an error,
system request, or SS message state.
Format:
04 72 (Hex)
Results:
Information associated with this command returns in the LU-LU nonexpedited
flow. What the user receives when they issue this command depends on the
condition of the master modified data tag (MDT) bit:
