Files System Help:
 
Files subcommands (Uploading requires access level 2 or higher):
  A - Ascii upload file to BBS (no error checks or masks)
  C - XMODEM Upload file to BBS (CRC mode)
  D - Directory of available (public) files
  G - Goodbye - sign off system
  H - Help file
  Q - Quit back to main BBS
  S - Send file from BBS (XMODEM protocol)
  T - Type file from BBS to caller (text dump)
  X - XMODEM upload
 
 - The IBM filename convention of using an 8 character filename with a 3 letter extension is observed.
 - The XMODEM (Christensen) file transfer protocol is supported, as well as a 2K upload capture buffer with XON/XOFF handshaking. The XMODEM protocol only works if both ends of the transfer are using a program supporting the protocol.
 - When uploading, the XMODEM protocol uses one of two error checking methods: checksum or CRC. Use the checksum upload ("X") option if you are unsure of whether your file transfer program can support CRCs.
