Hi All,
very strange problem. Heartbeat reset the baud rate to 19200 even though
the value in ha.cf is 115200. Also, no matter if I set it with stty,
when I start heartbeat it always reset the baud to 19200.

After several tries I found what the problem is. The line "baud" in
ha.cf must be BEFORE the line "serial". It's incredible how such a
stupid thing can block everything. I don't totally see the logic behind
this and why this is not documented. Maybe it is somewhere, but not
extremely noticeable at all.
Hope this can help someone in the future even if I think two lines in
the documentation would be very very handy. I strongly recommend this.
It is mentioned in the global option section for ha.cf at
http://www.linux-ha.org/ha.cf:
----------------------------------------------------------------------------
Global ha.cf options
It is important to note that certain options in the ha.cf file are
global in nature, and that ordering of these global options is important
in configuring the ha.cf file, since each directive is interpreted as it
is encountered in ha.cf.
These global options are:
*
use_logd <#use_logd>
*
logfacility <#logfacility> /- (deprecated)/
*
logfile <#logfile> /- (deprecated)/
*
debugfile <#debugfile> /- (deprecated)/
*
udpport <#udpport>
*
baud <#baud>
It is recommended that these options be placed first in the ha.cf file
when they are entered. In particular, placing the logging entries first
is especially recommended.
The default values for each of these pages can be found on the web
</ha.cf/DefaultValues>.
------------------------------------------------------------------------------
This doesn't mention the relationship between baud and serial, but in
fact when the serial directive is encountered, the HBcomm/serial plugin
is invoked and during init it looks for baud - if baud has already been
specified then that value is used, otherwise the default (19200) is
used. Probably could use a little clarification under the serial directive.

Jan
