+/** @file patest_wire.c
+    @ingroup test_src
+    @brief Pass input directly to output.
+
+    Note that some HW devices, for example many ISA audio cards
+    on PCs, do NOT support full duplex! For a PC, you normally need
+    a PCI based audio card such as the SBLive.
+
+    @author Phil Burk  http://www.softsynth.com
+
+ While adapting to V19-API, I excluded configs with framesPerCallback=0
+ because of an assert in file pa_common/pa_process.c. Pieter, Oct 9, 2003.
