PortOpen

Sets or Retrieves the state (open or closed) of the serial port.

MSComm32 and SComm32 have the same syntax and functionality.


Syntax:-

SComm1.PortOpen = value
 

value:-

A boolean expression indicating whether the port is open or closed
 

Example:-

SComm1.PortOpen = True

If SComm1.PortOpen = True
   MsgBox ("Port is Open)
Else
   MsbBox ("Port is Closed")
End If


Remarks

If you attempt to open a port that does not exist or a port that is already open then a trapable runtime error occurs.
