Help on Executive Host Protocols:

      (Z)modem - This advanced protocol is very fast and reliable.  Nice
      features such as auto-receive and crash recovery (allows the user to
      resume an interrupted transfer), make this protocol the best choice
      for most callers.
    
      (P)uma - An advanced external protocol similar to Zmodem.  It is
      also very fast and reliable, and has crash recovery to resume aborted
      transfers.  The 16550 UART is fully supported by Puma.

      (H)/S Link - This is a protocol that allows the simultaneous
      sending and receiving of files.  Chat is also possible during 
      transfers.  This is a very fast reliable protocol which provides
      crash recovery.

      (B)imodem - This protocol is on of the new bread of protocols that
      allows the simultaneous sending and receiving of files.  In addition
      a chat screen with wordwrap is active during file transfers.  When
      simultaneous transfers are taking place, effective transfer rates can
      be nearly doubled using Bimodem compared to other uni-directional
      protocols.

      (O)-MobyTurbo - This protocol is actually a modified Zmodem mode that
      is available via DSZ.COM.  Transfer rates are reportedly higher than
      Zmodem in most cases, without any sacrifice in Zmodem reliability.

      (J)modem - This external protocol is another relaxed Xmodem hybrid.
      Less frequent CRC checks and a data transfer windown that "streams"
      up to 8k in size yield a substantial gain over standard Xmodem rates.

      (Y)modem - This protocol is a variation of Xmodem which keeps the
      correct name, size, and date of the files being sent. It may use 128
      or 1024 byte blocks.

      (X)modem - Sends files in blocks of 128 characters at a time. When
      the receiving computer is satisfied that one block has arrived
      intact, it signals so and waits for the next block. Error checking is
      a Checksum or a more sophisticated Cyclic Redundancy Check.

      (1)k-Xmodem - This is a small variation of Xmodem that uses blocks
      that are a full 1k block in size.

      (G)-1k-Xmodem - This is a variation of 1k-Xmodem that is designed
      for error correcting modems and null modem cable links between two
      computers. It sends blocks one after another without waiting for
      acknowledgment from the receiver.

      Ymod(E)m-g - This protocol is a variation of Ymodem, which requires
      an error correcting modems or null modem cable links between two
      computers. It sends one block after another without waiting for
      acknowledgment from the receiver.

      (S)ealink - This is an advanced version of Xmodem that is 15 to 25
      percent faster than regular Xmodem. Sealink passes a file's name,
      size, and date when transferring.

      (M)odem7 - This is another Xmodem hybrid that passes the filename
      before starting the transfer, eliminating the need for it to be
      entered by the user.
