PupStringProxyExt is the proxy extension for either a PUP_String Point (read-only) proxy point or a PUP_StringWritable proxy point. Like any PupTypeProxyExt, it represents a single piece of data defined by a combination of the channel and the attribute in the channel, and has standard proxy extension properties such as Status and Enabled, among others (see “ProxyExt properties” in the Drivers Guide for related details). For additional details, see PUP proxy points.
