From 9e633f58da0e7a5e07da0becdd81b43ab2ea227c Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 27 Jun 2002 21:25:14 +0000 Subject: 2002-06-25 Thomas Doerfler * With the addition of serdbg, the standard polled I/O functions for gdbstub and/or printk are optionally routed to any termios-aware device driver, that supports polled mode. See libmisc/serdbg/README. * serdbg/Makefile.am, serdbg/README, serdbg/serdbg.c, serdbg/serdbg.h, serdbg/serdbgcnf.h, serdbg/serdbgio.c, serdbg/termios_printk.c, serdbg/termios_printk.h, serdbg/termios_printk_cnf.h, serdbg/.cvsignore: New files. * configure.ac, Makefile.am, wrapup/Makefile.am: Modified to reflect addition. --- cpukit/libmisc/serdbg/serdbg.h | 174 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 174 insertions(+) create mode 100644 cpukit/libmisc/serdbg/serdbg.h (limited to 'cpukit/libmisc/serdbg/serdbg.h') diff --git a/cpukit/libmisc/serdbg/serdbg.h b/cpukit/libmisc/serdbg/serdbg.h new file mode 100644 index 0000000000..3cc95b5b96 --- /dev/null +++ b/cpukit/libmisc/serdbg/serdbg.h @@ -0,0 +1,174 @@ +/*===============================================================*\ +| Project: RTEMS remote gdb over serial line | ++-----------------------------------------------------------------+ +| File: serdbg.h | ++-----------------------------------------------------------------+ +| Copyright (c) 2002 IMD | +| Ingenieurbuero fuer Microcomputertechnik Th.
