PHP comm port checker

Hello to everyone my name is eresbos,

Coded for ;

• I encoded it so that port errors could be resolved faster.

Comm port checker coded for your computer ports testing.If an error occurs when a device is added.You can solve it more quickly. If port is off you see this mesagge 'Your comm-port not active.Check your connection'. You can check the following port list :

• '2400',
• '4800',
• '9600',
• '19200',
• '38400',
• '57600',
• '115200',
• '230400',
