Create the resource id: Linux: Windows $path = (PHP_OS = ' Linux') ? ' /dev/ttyS1' : ' COM1' Īs I am not able access the COM port Value with references to Linux Server and windows server.So explain me what all setting need to made with references to Linux & windows Server.As this below code is working properly in localhost.Ĭommand Not found:mode /dev/ttyS1: BAUD=9600 PARITY=N data=8 stop=1 XON=off TO=onĭo you have some kind of shell remote login to your server (e.g. Change Parms on Comport: Linux: Windows $command = (PHP_OS = ' Linux') ? ' mode /dev/ttyS1: BAUD=9600 PARITY=N data=8 stop=1 XON=off TO=on' : ' mode COM1: BAUD=9600 PARITY=N data=8 stop=1 XON=off TO=on'
