Disable Password
   The  -b  option  will disable the user/password query in pro-
grams TELNET, RTELNT, FTP, RFTP, CNCT, RCNCT, MAIL,  and  MMAIL.
Local  users normally are not required to use passwords when ac-
tivating TELNET, FTP, or CNCT.  The MAIL and MMAIL programs  and
the  network  server programs RTELNT, RFTP, and RCNCT should not
specify the -b option for security reasons.  
Subdirectory Unit Selection
   The  default  LD units used by the client/server/utility pro-
grams  for  subdirectory  access  are  LD2:   and  LD3:.   These
defaults may be changed with the hidden -s option:  
        -s arg1 arg2
   where arg1 is the first LD unit number to use and arg2 is the
maximum number of nested subdirectories.  The value of arg1+arg2
must  be  less than or equal to 8, the total number of LD units.
The default is arg1=2 and arg2=2.
