ReplyOS is a read-only String property that represents the operating system identifier found in the response to an Ident query. ReplyOS can contain an empty string if the Ident response does not contain an explicit value. 

The value in ReplyOS is obtained by parsing the Reply property updated in the Query method. ReplyOS will normally contain one of the Id_OS constants which are defined in the IdAssignedNumbers unit. 

Use the ReplyCharset, ReplyOther, and ReplyUserName properties to access additional values that may have been present in Reply.
