Abstract
A point-of-sale (POS) system includes a POS host, a plurality of client devices, and a wireless transmission device. The wireless transmission device includes a host-end wireless communication module coupled to the POS host, and a plurality of client-end wireless communication modules coupled respectively to the client devices. The POS host is operable to configure the host-end wireless communication module for generating a plurality of virtual COM ports. Each of the virtual COM ports is matched with a respective one of the client-end wireless communication modules, such that the POS host is able to communicate wirelessly with the client devices through the host-end wireless communication module and the client-end wireless communication modules.

17. A data transmission method to be implemented by a point-of-sale (POS) system including a POS host and a plurality of client devices, the data transmission method comprising the steps of:
-
(A) coupling a host-end wireless communication module to the POS host, and coupling each of a plurality of client-end wireless communication modules to a respective one of the client devices; (B) using the POS host, configuring the host-end communication module to generate a plurality of virtual COM ports, each of which is matched with a respective one of the client-end wireless communication modules; (C) upon detection by the host-end wireless communication module that one of the virtual COM ports has received data from a matching one of the client-end wireless communication modules, configuring the host-end wireless communication module to send an acknowledge signal to the matching one of the client-end wireless communication modules; and (D) upon detection by one of the client-end wireless communication modules that data has been received from the host-end wireless communication module, configuring said one of the client-end wireless communication modules to send an acknowledge signal to the host-end wireless communication module. - View Dependent Claims (18, 19, 20, 21)
