Command Line CALLs
This chapter describes and illustrates CALLs that cause a function to occur within
the BASIC or BASIC-T module. These CALLs cannot be executed within the
BASIC program but are entered at the command line. Table 5.1 lists the
corresponding mnemonics.
CALL 73 –
Battery-Backed RAM
Disable Purpose
Use CALL 73 to disable the battery-backed RAM. When this CALL is executed,
the message
Battery Backup Disabled is printed on the host terminal.
Disabling battery-backed RAM allows a purging reset. When power to the module
is turned OFF, the contents of RAM are destroyed. When power is reapplied, RAM
is cleared and battery back-up is re-enabled.
