Exclusive Use Of Key, Initiation/Termination - SATO /gt Series Programmer's Reference Manual

Unit 4: Standard Command Codes

EXCLUSIVE USE OF KEY, INITIATION/TERMINATION

FUNCTION
Temporarily invalidates routine operator panel key entries and allows operator control.
FORMAT
<ESC>I#a
Place anywhere between <ESC>A and <ESC>Z.
EXAMPLE
<ESC>A
<ESC>I#0
<ESC>Z
OUTPUT
This command does not result in printer output.
NOTES
When the key is exclusive to the user, all the key entry information will be saved to the
key buffer. The key entry information is obtainable with Acquisition of Key Information
[SOH+KI].
This command is only enabled while online.
The key buffer size is 1KB. One key entry information requires 2 bytes and up to 512
information entries are available.
The key buffer acts as ring buffer. When the key entry exceeds the maximum entry
capacity, the oldest entry information will be overwritten.
When the exclusive use of key is initiated, the key buffer is initialized and vice-versa
when it is terminated. As a result, key entry information is obtainable following this
operation.
Label printing or label error detection will be performed as usual even when the
exclusive use of key is activated. Error occurance while the exclusive use of key is
activated will release the exclusive state. After recovering from the error and going
back online, the exclusive use of key will be active again.
Exclusive use of key is initially off when powering on the printer.
Key Entry (<ESC>IZ) is invalid when the exclusive use of key is activated.
