“41=1B284105006164050A0A” in the description above assigns the buzzer control command
ESC(A to “A”(code41) of control-A font. This data specifies the internal buzzer to beep five
times at intervals of one second.
Save the TMCTRLA.INI under the following system folder.
Windows 95/98 :\windows\system
Windows NT :\winnt\system32\spool\Prcpocs\W32x86
Then describe as follows in your program.
