RS232 via TCP

[CaM]

hi, has anyone been able to send RS232 commands via TCP?

The serial pluging only does com ports.

I can use Hyperterminal to send commands ok; but Hyperterminal does not work on the command line.

thanks

You lost me there.. send RS232 commands via TCP? Do you have an ethernet <-> Serial converter or..?

If you do then it's just a matter of making a TCP client script that knows how to talk to your device, it should be pretty simple since I suspect this is just a straight forward telnet type deal. Take a look at the vlc plugin, zoom player plugin, lirc client, web server or any of the other plugins that use tcp/ip for some examples. It's not that difficult but you'll have to program it yourself.

Keywords for what you are looking are: python, asynchat, asyncore.

PS. Depending on how simple your protocol is might even get away with using something like netcat and piping some data through it for a super-simple command line implementation. (though the the real EG plugin will be much nicer if you decide to go that way)

hi, my projector allows control via TCP.

This works the same way as serial (RS232) but I specify an IP and port instead of a COM.

I will do some coding

thanks for your help.

That would be called... telnet, or at least a dumb text socket. I do not see a plugin for this currently, however it should be fairly trivial to write a plugin for that.
