Due to a very complex network environment I need a Mobile ASPx APP can comunicate with a Unitech PA962 portable terminal running Win CE .NET 4.2.
That communication must be established to print over a Cameo2 Zebra Bluetooth printer.
The PDA has a AnyCom Bluetooth CF-300 and a Orinocco 802.11b card on it.
From the Web application I'm sending a string with the information to print, (command secuences and variable data) using a tcpclient over a tcp port pointing to the PDA's IP address.
Since I can't use XML WS inside the PDA I'm thinking on build a Windows Service that runs un the PDA, that WinService will be "listening" to that port for incoming connections, when a connection is detected It will take the string and send it to the Bluetooth card virtual COM Port.
Is it possible to solve that scenario with a windows service running on the PDA?
Any suggestions about a better schema?
Windows services programming is the same, even for windows CE.Net?
if there a place where I can download tutorials about windows services programming?

Please, any help will be very important.
T.I.A.
