Don't use localhost to accept external connections tsockopt(socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1) tsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) Sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) Remove first line if don't want to use is as auto executable script #!/usr/bin/python I've done this small python program, can be useful. You have socat and ser2net and other programs but my experience is very bad.
My question is, how can I create a TCP server that has a virtual serial port attached and can send/receive data through this port over TCP to listening clients?
However I want to solve this problem on linux machines. On windows I used a virtual serial port connector which did most of the work. To forward ports in VirtualBox, first open a virtual machine’s settings window by selecting the Settings option in the menu. The response from the clients is send over TCP back to the server which can read it over the virtual serial port. When an application on the server writes data to this port, the data should be send to all clients connected via tcp. But buddy I think it's easier to user USB to serial converter.
#USE COM5 PROT ON UBUNTUE 16 ON VITUAL MACHINE INSTALL#
sudo apt-get install socat Creating ports socat PTY: PTY: That should create and link the virtual port pair for as long as socat is running. The server has a virtual com port, the same we set in the client config (e.g. 1 To create a pair of ports you will need a utility called 'socat'. The client then will automatically try to connect to the server. When we setup a client, we have to provide the IP address of the server, a tcp port (usually 8080) and a virtual com port. The client can establish a TCP connection to a server. I am new in using serial ports and I have some questions on this topic. I am developing an application that should be able to write to a virtual serial port and receive data through the same port from remote clients over network.
