ParityReplace

Sets or Retrieves the character that will be used to replace bytes which have failed a parity check.

Available at design time and runtime.

MSComm32 and Comm64 have the same behavior

         Syntax object.ParityReplace = value
     
  object Name of the communications control.
  value A character/string expression indicating the ParityReplace character
     
  Example object.ParityReplace = "?" '// Set the value to the default.
       
    object.ParityReplace = "" '// An empty string
       
    Text1.Text = object.ParityReplace '// Retrieves the value
       

Remarks:

If parity is enabled (see the object.Settings property) then the com port will complete a parity check on each byte as is it received. If this property is enabled then any byte failing that parity check will be ignored and replaced by the ParityReplace character.
