Posted July 13, 200717 yr With our application we tryed to open com1 while using the on-screen keyboard. The port couldn´t be open. The device manager didn´t show the use of the port. Instead of our appliction we tryed it with hyperterminal. The message was "com1 is occupied from another application". After closing the on-screen keyboard hyperterminal was able to open the port. Is it a known bug ? How to fix it (using both com1 and on-screen keyboard) ??
