Umm... you are attempting to upload a file via a satellite receiver?
Well, I'm not especially familiar with radio transmission, but from what I understand, a receiver can't transmit with the hardware available to it. You need transmitting equipment.

Unless you mean something along the lines of firmware. Then you need to consult your manual.

Right, here goes.

a) Normal serial port: /dev/ttySx

b) USB serial port: /dev/ttyUSBy

"Set your port to use /dev/ttyUSB0": change a) to b) in whatever is trying to talk to the serial port. That is what the original poster you linked to was saying, and he is assuming you're connecting to a modem hence his reply about a dialler.

If you are trying to flash firmware, make sure that you are aware that if something goes wrong you have created a very expensive paperweight, and adding a USB<->Serial converter is adding another item in the list of things that could go wrong.

I Had to re-install windows to do the firmware flash.

i have a laptop, so there is no serial port on it, windows picks it up automatically that the usb is used for the file transfer ..etc...

i was hoping that there is a way to change it by default on laptops that any serial port communication is going via USB.

i understand that we can change it in the tool (for modems) but what about other tool that have it hardcoded in the software ...is there a way to do the change from the O.S instead of the application?
