  Hi to everyone. I wrote a program in C# that implements a RS232 communication but I decided to use not the Framework SerialPort class. The reason of this choiche is the need to replicate a specified output sequence obtained by a serial port monitor (I use this free [serial monitor](http://www.serial-port-monitor.com/Download/free-serial-port-monitor.exe)): Output to replicate: 0,IRP_MJ_CREATE,DOWN,TRUE,0x0,..., 1,IRP_MJ_CREATE,UP,FALSE,0x0,,, 2,IRP_MJ_DEVICE_CONTROL
