With wireless RS232, either serial infrared
or radio frequency (RF), the wireless signal is converted back
to regular RS232 by the receiver so the data appears in exactly
the same way whether it has come through a serial cable or
wireless. Most RF systems allow 2-way transfer of data and
commands so the serial communication software needs to support
2-way communications. Standard Windows serial communications
programs such as Hyperterminal communicate bi-directionally
and so do many other applications that already support serial
communications. However if you want the wireless serial data
to be input real-time in your other Windows applications such
as MS Access you will need WinWedge from
TALtech. This provides bi-directional RS232 (wireless or with
a cable!) from within any Windows application.
With Wireless Ethernet most hardware providers also provide
a converter software driver that creates a Virtual serial
port and makes the Ethernet data available as RS232. If the
manufacturer does not you can use TCP-Com from
TALtech to create a virtual com port on the PC and make the
Ethernet data available to any RS232 supporting application
(or any other application using WinWedge). Or you can use TCP-Wedge also
from TALtech to input the Ethernet data directly into Windows
applications that have no Ethernet or serial support such
as MS Access.
The Bluetooth Wireless RS232 adapters basically
behave just like standard RS232 serial ports on a PC except
that there are no wires. So again you can use existing serial
communications applications to collect data from your wireless
devices including WinWedge software.
