CLLCD

Command

 

 

 

Type:

 

 

 

Description:

Clear LCD Command: Clears (blanks) the stack display.

 

 

The menu labels continue to be displayed after execution of CLLCD.

 

When executed from a program, the blank display persists only until the keyboard is ready for

 

input. To cause the blank display to persist until a key is pressed, execute FREEZE after

 

executing CLLCD. (When executed from the keyboard, CLLCD automatically freezes the display.)

Access:

!°LOUT CLLCD

 

( °is the left-shift of the Nkey).

Input/Output:

None

 

 

 

Example:

Evaluating « CLLCD 7 FREEZE » blanks the display (except the menu labels), then

 

freezes the entire display.

CLOSEIO

Command

 

 

 

Type:

 

 

 

Description:

Close I/O Port Command: Closes the serial port, and clears the input buffer and any error

 

messages for KERRM.

 

 

 

When the calculator turns off, it automatically closes the serial port, but does not clear KERRM. Therefore, CLOSEIO is not needed to close the port, but can conserve power without turning off the calculator.

Executing Kermit protocol commands automatically clears the input buffer; however, executing non-Kermit commands (such as SRECV and XMIT) does not.

CLOSEIO also clears error messages from KERRM. This can be useful when debugging.
