Customer have a cash drawer and I can't access it thru the POS software, I contacted the Cash Drawer supplier, it test using the following method and another method I get it from internet and tested it also work and able to open the cash drawer here the step:
1)Exit
from your application software.
2)Shell
out to the MS-DOS command prompt or restart computer in DOS mode. At the DOS
prompt,
3)
enter “MODE COMx 96,n,8,1” (excluding the “” marks; x=1 or 2 depending upon
which port you are hooked up to).
4a)On
the next line enter “TYPE CON>COMx”.
After
that, on the next line hold down Ctrl and hit G. Then, hit Enter. The drawer
should open if you haven’t changed any of the default switch settings inside
the drawer. If this still does not work, make sure the switches are set to
their default settings and that the power supply adapter is working. If you get
a “Write fault error to COM port”, close any other software that are set to use
the same COM port and then try again (check Autoexec.bat file
to see if a LPT printer port is redirected to the COM port).
If this test opened the drawer, go back to your application
software and check the port settings for COMx, 9600 baud, no parity, 8 bit data
and 1 stop bit, and drawer opening code is Ctrl-G (hex 07). You may need to
refer to your software user manual or contact your software supplier for
assistance.
4b) create a txt file with any word in side ( type 1 in the
text file and save as 11.txt on c:\)
Then after step (3) then type copy 11.txt com3, the drawer
will open.
