This is something unusual I am doing other than coding. So My question is bit tricky and for those who have some knowledge of hardware programming I think so.
So all I am doing is, I bought one web Relay device from Hw group and it's called IP Relay ER02b. Which has two inputs 1 & 2 and that I am controlling through command prompt like on/off using web relay device IP address.
However, I have one more pin-pad device which is connected to web Relay into port called RS232. So there is no direct connection to my laptop with pin-pad device.
So the question is, how I can read incoming pin-pad numbers using IP address of web relay using command prompt as I searched a lot and couldn't find the way to do this using command prompt or PHP as PHP is also fine.
Any help on this will be appreciate and if need any further information then please let me know and I'll more than happy to provide.
Thank you guys in advanced
