/*  History

Old Log (for new changes see ChangeLog):

Revision 1.2  2003/10/03 14:56:40  gernot
- partly implementation of a bigger semantic change: don't throw
  call finished exceptions in normal operation any longer; i.e. we only
  test for the connection at the begin of a command. This allows return
  values, e.g. for commands like capisuite.fax_receive() which were
  interrupted by an exception always in former CapiSuite versions and thus
  never returned. This is also a better and more logical use of exceptions
  IMO. ATTN: this is *far from stable*

Revision 1.1.1.1  2003/02/19 08:19:53  gernot
initial checkin of 0.4

Revision 1.8  2003/02/10 14:08:21  ghillie
- cosmetical log improvement

Revision 1.7  2003/01/19 16:50:27  ghillie
- removed severity in exceptions. No FATAL-automatic-exit any more.
  Removed many FATAL conditions, other ones are exiting now by themselves

Revision 1.6  2002/12/18 14:46:23  ghillie
- removed done TODO

Revision 1.5  2002/12/06 13:13:06  ghillie
- use Connection::getState() insted of Connection::isUp()

Revision 1.4  2002/12/05 15:56:24  ghillie
- added checks for connection state to throw exception if connection is down

Revision 1.3  2002/11/29 10:29:12  ghillie
- updated comments, use doxygen format now

Revision 1.2  2002/11/25 11:58:53  ghillie
use service_type instead of hardcoded CIP values now

Revision 1.1  2002/11/22 14:59:36  ghillie
initial checkin
