I am using the PC connectivity SDK 3.0 on windows2000 through IrDA on 6210. I tried to use the SMS Edit and it is working fine except the Write SMS and SMS Setting. By clicking on Setting SMS I get an error message as the following "Error number 7690 in From_Refresh" and if a fill the setting and click on Apply an error message pups up with a message "Error number 7690 in From_Apply". Where if I click on Write SMS a get the following Error message "Error number 7690 in getting SMS setting". Would you kindly help me in this issue, thanking you in advance for your kind attention.
