CVS Socket comunication problem

[jazzvale]

We are developing a Java CVS client comunicating via Socket with
cvs-server.
All works good, but we don't know how to recover a file that has been
deleted.

The problem is that we don't know how to retrieve the names of the
files that has been deleted for a folder (is there a way to log a
whole folder and retreive allso the names of the deleted files?).

Further this: how do we get the stream of a deleted file? We can't
perform an update ... this is an example of an our comunication:

C: BEGIN AUTH REQUEST 
C: d:/cvs3 
C: admin 
C: Aye%?= 
C: END AUTH REQUEST 
S: I LOVE YOU
C: Root d:/cvs3 
C: Valid-responses E M ok error Valid-requests Merged Updated
Update-existing Removed Remove-entry New-entry Checked-in Checksum
Copy-file Notified Clear-sticky Set-sticky Clear-static-directory
Set-static-directory
C: UseUnchanged  
C: Directory . 
C: d:/cvs3/rep1/vers1/pirla 
C: Entry /phile7.txt/1.1/=// 
C: Argument phile7.txt 
C: update 
S: E cvs server: phile7.txt is no longer in the repository
S: Removed ./
S: d:/cvs3/rep1/vers1/pirla/phile7.txt
S: ok 

phile7.txt is the file that we're trying to recover, but it seems that
cvs doesn't want to retreive the version 1.1 of this file!!!

Does anybody can help us? Is some documentation avialable somewhere?

Thanks 

Valerio

Note: We're running the latest version of cvs-server on WINNT.
