Uploading the whole directory to the server...

[Loo, Peter # PHX]

Hi,

Can someone please tell me how I can upload a whole directory structure from
my PC to my server using ssh (rz)?  I can upload files, but am unable to
copy the whole directory and sub-directories within the parent directory.
The version of ssh I am using on my server is:

SSH Version 1.2.27 [i686-unknown-linux], protocol version 1.5.
Standard version.  Does not use RSAREF.

The client software I am using is SecureCRT.

Thanks.

Peter
