Retrieving messages from the BACKUP SERVER?

[GaryAshford]

Hi.
Does anyone know how the CS-LIB or CT-LIB API can be used to retrieve the information returned by the BACKUP SERVER when executing a "dump database" command??

If you execute this from isql, you get the full story, e.g:
Backup Server session id is: 11. Use this value when executing the
'sp_volchanged' system stored procedure after fulfilling any volume change
request from the Backup Server.
Backup Server: 4.41.1.1: Creating new disk file /tmp/spr96db19.dump.
Backup Server: 6.28.1.1: Dumpfile name 'spr96db191990AC34' section number 0001
mounted on disk file '/tmp/spr96db19.dump'
Backup Server: 4.58.1.1: Database spr96db19: 238 kilobytes DUMPed.
Backup Server: 3.43.1.1: Dump phase number 1 completed.
Backup Server: 3.43.1.1: Dump phase number 2 completed.
Backup Server: 4.58.1.1: Database spr96db19: 242 kilobytes DUMPed.
Backup Server: 3.43.1.1: Dump phase number 3 completed.
Backup Server: 4.58.1.1: Database spr96db19: 246 kilobytes DUMPed.
Backup Server: 3.42.1.1: DUMP is complete (database spr96db19).

If I execute it using ct_command and ct_send, the only information I can get back (via ct_diag) is:
Backup Server session id is: 11. Use this value when executing the
'sp_volchanged' system stored procedure after fulfilling any volume change
request from the Backup Server.
Backup Server: 4.41.1.1: Creating new disk file /tmp/spr96db19.dump.

Whatever I try, I cannot get at the BACKUP SERVER status messages.
