Input Commands Input commands consist of immediate and AID-associated Read commands. Immediate commands are executed when the controller receives the command. AIDassociated 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. Description: Read Immediate 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. Note: If the display supports a separate message line, and the message line is selected, the command is rejected only for the system request and SS message states. The command is processed with the display in error state. Format: Results: 04 72 (Hex) 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: 16 Intermec Terminal Emulator (ITE) Programmer's Reference Manual
