RS232. Any opensource or freeware. I tested a fews but is shareware. Which is the best of them? i like to send commands and snif all communictions betewen the receiver and computer. I like to do this to interact with a linux box.
You need a nullmodem cable (cross) for communictation not a normal rs232. check your device manager and see how many ports com you are. If a desktop then normaly is port COM1 or COM2 (choose in settings of your program). If you have a usb2rs232 then you need to install the correct drivers and when you atach the cable you see a message in taskbar of port what you use.
See if you have the right program. Turn on your receiver (many dont upgrade in standby). GOOD LUCK
