i recomment not to use mscomm32.ocx,it sometimes does not work well in windows 2k and windows xp,you can use class CSerialPort that can be download from internet

one method is to rename the ID of button "OK",don't use IDOK. another method is to define a function for press button "OK",in the function, delete the line"CDialog::OnOk().

anyone know it? thank you?
