Modbus rtu on colibri wince

Hello all,

Has any one used MODBUS RTU on WinCE6?
I have got demo code from Toradex itself.

I have been testing it using MODSIM( VF61 as master and Modsim as slave device) application which is used for basic testing of modbus libraries.

But using this code, i’m not getting data on modsim. Communication parameters are matched and communication setting is successful…

Has anyone worked on this? Can i get tested drivers for modbus rtu for wince?
