MINIMUM BAUD  FOR  LOGON  allows  you to set the lowest baud
    rate for a user to log on  to your system. Calls at 300 baud
    may be restricted by using  the  NO 300 START and NO 300 END
    options.  To  disable  this  option,  set both start and end
    times to 00:00.

    You can also limit file downloads in the same way.  However,
    this  option differs slightly in that the MINIMUM  BAUD  FOR
    FILE TRANSFERS applies all the time.  The DOWNLOAD START/END
    times  specify times during which downloads may occur.  Note
    that  this  time  restriction may be cancelled  for  certain
    users  by  setting  a flag in their  user  record.  See  the
    section on USERS for more on this.                                                   .
