THE UPLOAD MENU OPTION

 The 'Upload' option allows the caller to send a file to the
 host. The caller is shown the following menu (here slightly
 compressed so it could fit):

  Modem7 SEAlink Xmodem 1k-Xmodem G-1k-Xmodem Ymodem Ymodem-g
  Which protocol?

 and should select the appropriate protocol by its first letter
 (or 'E' for Ymodem-g). If appropriate the caller is also asked
 for the filename. The transfer is then initiated. Level 1
 callers may only upload files into the 'Host Upload Directory'
 defined with HCONFIG.
