access local com port from a remote server

Question

I have a custom POS system in PHP (on a remote server), which requires displaying the price on a Pole display device, which is connected through com port (on the local PC).

I want a way to access the local com port from a remote server.

Is that applicable?

@Dagon, is there's any work around for this? I mean using Javascript or any other language. — CairoCoder

seems like your approaching this with the wrong language set, the pc with the com device should be running an application to communicate with the remote server — user557846

does google serial help with this? developer.chrome.com/apps/serial — CairoCoder

You can buy a serial over ethernet device which will convert the serial stream to TCP/IP in both directions. Then you can use a socket in your PHP/server side to talk to it. I have had good luck with Lantronix devices. lantronix.com/device-networking/embedded-device-servers/?tab=0 — Shane Wealti
