srcpd-2.0.11 (2008-01-27)
Fixed Bugs
o Fixed »switch power on« bug for DDL module.
o Fixed microsecond value for GA initialization.
o Fixed wrong milli-second format for INFO GA (was e.g. »x.6«
instead of »x.006«)

o Disabled writing to 'stderr' during normal operation, this fixes
broken debian package updates and srcpd misbehavior in SuSEs
runlevel editor.
o Fixed daemonization, process now is detached from controlling
terminal properly.
o Fixed a lot of not closed file descriptors, free memory allocated
for configuration data, free used mutexes and condition variables.
This prevents srcpd from eating system resources.
o Fixed system freeze on Linux 2.4 kernels using ddl-module.... read more

As of today most of the historical code is transferred to Subversion code repository.

The conversion could not keep all data and all old states. Some files deleted long long ago (aka moved to Attic) may be lost forever, so do not expect that the old branches may build the binaries.

CVS is still active but should _not_ be used for active development any more.

SRCP now has it's own portnumber and protocol name.

srcp 4303/tcp Simple Railroad Command Protocol
srcp 4303/udp Simple Railroad Command Protocol

This release adds basic loconet support and provides enhancements for Selectrix and LI100. Some internal
changes for better support of Linuxx kernel2.6 and
64 bit architectures.

From the SRCP 0.8.3 the SET FB feature was implemented. Most
useful for the loopback bus, others may suffer from hardware
support.

Not to forget numerous bugfixes and stability improvements.

Binary packages are provided when they are made.

notably changes since SRCP 0.8.2
- no more wildcards (no one ever implemented them, they are really difficult)
- handshake phase has a new error code 410
- time stamp may be derived from TIME device or a simple counter, not
all systems habe a system time
- GA may use Seletrix
- FB may be set via protocol
- changed sgml to docbook xml, translated into (some kind of) English

Release 2.0.9 of the srcpd is ready
most important changes are
- default values for all parameters

- major ddl enhancements

- cygwin (Windows) Support

- major code restructuring

- minor internal cleanups and the usual
bugfixing.

The URL http://srcpd.sourceforge.net/srcpd/cfg/ provides a simple but comfortable config file generator. You may simply select the devices you want to attach with there respective settings and it will give an ready-to-use config file.

Any comments and wishes direct to the mailling list srcpd-devel@lists.sourceforge.net.

For the major architectures we provide debian packages of
the current srcpd version. These packages are mostly
untested and do need feedback from users.

Major Enhancements
- Support for selectrix based systems
- Support for ZIMO devices
- full GL device group support
- temporarily dropped GA (till next release?)
- varios improvements for LI100 (Lenz)
- i2c connections made more flexible
- hsi-88 improvements
- DDL (Digital Direct for Linux) integration
- short detection
- automatic deactivation of GA after specified delay
- emergency stop for GL (M protocols)
Minor changes
- XML configuration ignores property number for definition of
busses. They are simply numbered as they appear in the configuration.
- internal changes for better portability and stability

Johann Vieselthaler has ported the NMRA programmer
to SRCP 0.8 and made a nice GUI for it. Please see the
screenshot section to get an impression.
