The following information summarizes the full NetBIOS parameters
in the NetBIOS Supplement and Programmer's Guide.  The
information on the /C parameter was taken from the 3+ 1.3
Administrator's Notes.

 KEY:
   B - Buffer Space
   T - Tables Space
   Avail - Available memory on the PC


 Param.  Description               Range  Default  Memory Required
 ------  -----------               -----  -------  ---------------
 /T      Transmit Buffers          2-Avail   4     240 bytes (B)
         (Session and Datagram)
 /R      Session Receive Buffers   3-Avail   3     1680 bytes (B)
 /D      Datagram Receive Buffers  1-Avail   1      580 bytes (B)
 /S      NetBIOS Sessions          1-240     32     216 bytes (B)
         (# of concurrent sessions)                 138 bytes (T)
 /N      Network Control Block     1-255     32     136 bytes (T)
         Commands
         (# of concurrent commands)
 /P      NetBIOS Processes         2-Avail   2     1024 bytes (T)
         (# of processes available
          for NetBIOS commands and
          asynchronous events)
 /W      NetBIOS Threads           1-Avail   1     1024 bytes (T)
         (# of wait commands to be
          processed at one time)
 /A      Cached Addresses          0-255     2       28 bytes (T)
         (# of remote networks to
           be used as internetwork
           names in the local 3NB table)
 /L      # of 3NB Use Commands     0-999     2       34 bytes (T)
 /I      # of 3NB Reg Commands     0-999     2       34 bytes (T)
 /C      Display Retrying Message  Y or N    Y     None
         (This is used on 3+SNA,
           Rabbit, Maxess, CXI,
           IBM 3270, and IrmaLAN
           gateways)
 /M      PC LAN Multitasking       Y or N    N     None
         (This is used for 3+SNA
          and Rabbit gateways)
 /H      IBM 3270 Support Emul.    Y or N    N     None


NetBIOS allocates 64KB of system memory for buffers and another
64KB region for tables (to hold information about sessions,
processes, commands, etc.)

The Redirector must have a machine name set to work properly.
The machine name, which can be 1-15 alphanumeric characters long,
is set by the program SETNAME.  3Com's recommended setting is
$$3Com$$, which sets the machine name to the hardware adapter's
address.

The /C switch determines whether the "Network retrying..."
message will be displayed when a network timeout occurs.  The
default setting is not to set the /C switch, so you can stop the
retry process by pressing Ctrl-Break.  You have the option to
keep the session or not.

When a NetBIOS application relies on getting the timeout errors
as a normal part of its operation, using the /C switch
immediately returns the timeout error to the application without
displaying a message.
