A.2.11 Can PSCP or PSFTP transfer files in ASCII mode?
Unfortunately not.
Until recently, this was a limitation of the file transfer protocols: the SCP and SFTP protocols had no notion of transferring a file in anything other than binary mode. (This is still true of SCP.)
The current draft protocol spec of SFTP proposes a means of implementing ASCII transfer. At some point PSCP/PSFTP may implement this proposal.
