+/** @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.
