+/** @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.
+

+    
+ 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.
