From c4337d812b22bc1746f579b416daba5013a43757 Mon Sep 17 00:00:00 2001 From: "David A. Mellis" Date: Thu, 29 Nov 2012 13:48:01 -0500 Subject: Moving TXCO definition into HardwareSerial.cpp from HardwareSerial.h. Otherwise, you get an error when compiling for processors with no serial port because the header file is always compiled.
