I am wondering if there is already available what I am needing? My situation is the following:
I have a remote installation of a measuring equipment, which communicates through RS232 to an RPi3 interface unit. On that there is a service that handles the data sent both ways. But it is geared towards automatic operations so there is no direct connection to the target system. Now I have a need to debug a Windows application that is also designed to talk to the same type of equipment via RS232. But the problem is that I am across the ocean from the equipment, so I need to insert some network link between me and the remote system. I have a VPN connection to the remote location so I can work on the RPi3 command line (and actualy also via VNC on the GUI). So a socket client/server solution seems possible. What I want to do is this: - close down the existing service on the RPi3 that handles the data recording. - Use an RS232 <=> TCP/IP socket service on the RPi3 to transfer data to/from the device - Set up a TCP/IP socket <=> RS232 handler on a local RPi4 in my location - Connect the Windows RS232 to the RPi4 by wire - Use the application under debug normally via RS232 from Windows but have the RPi pair move the data between the endpoint RS232 connections via TCP/IP through the VPN connection. Before I start coding the RS232/Socket interface server and client parts myself I would like to know if someone here knows about an already existing Lazarus open source project that implements my wanted functionality? -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
