Re: Recieve from SerialPort from Another Machine 9 Years Ago by SalmiSoft I think you'll need to have some software running on the machine which physically has the serial port. You could write that software yourself, or buy it (eg http://www.advancedvirtualcomport.com/index.html). Re: Recieve from SerialPort from Another Machine 9 Years Ago by JOSheaIV Yeah I assumed I might, any idea how I would got about though writing it? I know how to use the Serial Port, but is there anyway to pull that data from another machine using say an IP address? Re: Recieve from SerialPort from Another Machine 9 Years Ago by SalmiSoft I would set the machine that has the physical serial port to be a server (use TcpListener?) and the remote machine to be a client (use TcpClient?). Then the client can send stuff to the server for the server to send to the device attached to the serial port, and the server can send back whatever it receives from the serial device. The server doesn'… Re: Recieve from SerialPort from Another Machine 9 Years Ago by SalmiSoft I am lost. How is your device connected? Serial line? (RS232 or something else?). Network cable? Wifi? If the device is connected via a network cable or wifi, can you ping it? Re: Recieve from SerialPort from Another Machine 9 Years Ago by rubberman If you are using physical serial ports (even via USB) then IP addresses are irrelevant, and not used. You need to connect to the correct COM: port. Re: Recieve from SerialPort from Another Machine 9 Years Ago by JOSheaIV Oh man I totally forgot about this. The device is a scale, but instead of hooking up to a standard serial port (like to a PC), it's hooked up to what I think was a wireless transmitter for like WiFi. Unfortantly I have to go back on site to work with the device. So for now I am at a stand still.

Re: System.IO.Ports.SerialPort Question!! 13 Years Ago by ecloney well, its amazing that after 74 views nobody has a response to this, what turned out to be an easy problem. as i am new to vb.net the syntax briefly eluded me, but after some research i found that if i passed an argument as a byte array, it would not convert to ascii, as when i passed it a string (by default).
