(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.
