//* Function: Trivial File Transfer Protocol Server start
//*
//* Please note:
//*
//* -a  Specify an archive directory.  TFTPD treats files in this
//*     directory and its subdirectories as binary files for uploads
//*     and downloads, regardless of how they were requested by the
//*     client.  Use this option on EBCDIC machines that act as file
//*     servers for ASCII clients.
//*
//*     You can specify up to 20 -a options, one directory per -a
//*     option.  You must specify directories as absolute pathnames.
//*
//* -c  the number of threads to use concurrently.  Make the number
//*     a some reasonable number like 20 and not the default, which
//*     is 200.
//*
//* -t  Set the packet timeout. The TFTP server usually waits 5 seconds
//*     before presuming that a transmitted packet has been lost. You can
//*     specify a different timeout period in seconds.
//*
//* -l  Log all incoming read and write requests and associated
//*     information to the system log. Logged information includes the IP
//*     address of the requestor, the file requested, and whether the
//*     request was successful.
//*
//* -p  Specify the port. The TFTP server usually receives requests on
//*     well-known port 69. You can specify the port in which requests
//*     are to be received.
//*
//* -r  Set the retry limit. The TFTP server usually limits the number
//*     of retransmissions it performs due to lost packet to 5. You
//*     can specify a different retry limit.
//*
//* -s  Set the maximum block size that can be negotiated by the
//*     TFTP block size option. The default is 8192.
//*
//* -f  Secify a cache file. You can specify a file containing
//*     information on files to be preloaded and cached for transmission.
//*     A cache file consists of one or more entries. For clarity, place
//*     each entry on a separate line. See the IP Configuration Guide for
//*     details on this option.
//*
//* -b  Specify IP address. The TFTP server usually binds to in6addr_any
//*     or inaddr_any. You can specify the IP address on which requests
//*     are to be received.
//*     TFTP requests that come in on other IP addresses will not be
//*     accepted by this instance of TFTPD.
