CLLCD

Type: Command
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.)

CLOSEIO

Type: Command
Description: Close I/O Port Command: Closes the serial port, and clears the input buffer and any error
messages for KERRM.
When the hp49g+/hp48gII 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 hp49g+/hp48gII 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.
