您可能需要检查代码是否正确-请参见

You may need to check if your code is correct - see here.

You should also try and get hold of the documentation provided by your supplier and check if the codes you are using are correct.

听起来像您在POS系统上工作，尝试过OPOS吗?这些是现金抽屉，扫描仪等的通用驱动程序".
为了提供更多帮助，我需要了解POS的硬件设置，品牌和型号等.

Sounds like you''re working on a POS system, have you tried OPOS?? those are the generic "drivers" for cash drawers, scanners, etc...
to help more I''d need to know how the hardware is setup, brand and model of the POS, etc.
