Wrong values of TerminalInfoInteger on Linux

[linux80s]

Hi,

I tried these TerminalInfoIntegers, but without success:

TERMINAL_MEMORY_PHYSICAL	Physical memory in the system, Mb	This gives wrong value
TERMINAL_MEMORY_TOTAL	Memory available to the process of the terminal , Mb	This gives wrong value
TERMINAL_MEMORY_AVAILABLE	Free memory of the terminal process, Mb	This gives wrong value
TERMINAL_MEMORY_USED	Memory used by the terminal , Mb	This gives 0 (zero)

Anyone who are using Linux can confirm these statements above?

Thanks
