(BI)directional Transfer
------------------------

Subcommands:  (filename) Names of file(s) you wish to download
			 (extension is not required if file's extension is
			  one of the supported compression types)

Description:  Allows a bidirectional transfer, which transfers files
	      simultaneously between you and the BBS.  After UltraBBS
	      determines your protocol type (usually BiModem), you will
	      be prompted for the filename(s) you wish to receive.
	      After the transfer, UltraBBS will automatically determine
	      if/what files were uploaded, and prompt you for their
	      descriptions and directory number.  Consult your local
	      sysop for more details on bidirectional transfers.
