Sorry that I missed the original post. Here's another approach to consider.
AnzioWin, our terminal emulator, contains two features that can address this need. First, we have bidirectional AUX support compatible with the terminals we emulate. You would attach the scale (or other serial device) to any Windows serial port on the associated PC. Then configure Anzio for this port. In operation, your host program would send out one escape sequence to go into bidi AUX mode, then send data to and read data from the device, then send out another escape code sequence. Note that the program reading the scale must be programmed specifically for this application. The second feature is called "backchannel aux". We allocate another channel within an SSH session for bidirectional serial communication. A PTY is assigned on the host end. On the PC end, we connect the backchannel to a specified COM port. On the host end, a program that does I/O to a pty port works without modification. Because all communication is over SSH, it is authenticated and encrypted. More info on request.
