Sets and returns the communications port number.
Syntax
object.CommPort[ = value ]
The CommPort property syntax has these parts:
| Part | Description |
| object | An object expression that evaluates to an object in the Applies To list. |
| value | A integer value specifying the port number. |
Remarks
You can set value to any number between 1 and 16 at design time (the default is 1). However, the MSComm control generates error 68 (Device unavailable) if the port does not exist when you attempt to open it with the PortOpen property.
Warning You must set the CommPort property before opening the port.
