USB->serial->USB adapter needed
I am trying to send RS232 data from two notebooks that do not have
serial ports. I know there are USB to serial (RS232) adapters
available. These allow communications to occur through a virtual
serial port. Now, what I need is a USB to USB RS232 serial cable, that
allows serial transmissions to occur, but via USB connections.
Can someone please point me in the right direction?
