Hello,

i'm projecting to connect a weather station davis vantage pro2 data collector with USB thru an Asus WL-HDD to connect remotely to the USB port.

Do you have any hints what packages i will need ?

Thank you, Peter.

i don't exactly know the device you're trying to connect but ... i have a hunch that the device uses a usb-serial module. it's just a hint-hunch ...
you still have to screen your serial communication and maybe simulate a serial port over the client part...

There is also a package called ser2net which I have used to connect to the serial port through TCP. What can be done with screen? I only recall using screen for having multiple shells running in a telnet session (like you get multiple desktops on *nixes but for shells).
