I repeat:

...what command(s) do you use to restart the service? What do you want the script to do that can't be done by putting the command(s) you use to restart the service in a file and executing that file?
And, how do you determine that "the service" does not send a packet?

Name
       tftpd - DARPA Trivial File Transfer Protocol (TFTP) server

Syntax
       /usr/etc/tftpd [ -r pathname ]

Description
       The  server, supports the DARPA Trivial File Transfer Protocol (TFTP).  The TFTP server is invoked when receives a packet on the port indi-
       cated in the TFTP service description.  The server is not normally started by default from

       The use of does not require an account or password on the remote system.  Because of the lack of  authentication  information,  will  allow
       only  publicly  readable  files	to  be accessed.  This extends the concept of public to include all users on all hosts that can be reached
       through the network.  This may not be appropriate on all systems however, and its implications should be considered  before  enabling  TFTP
       service.

       The server should have the user ID with the lowest possible privilege.

Options
       -r pathname    The pathname can be the choice of the user.  For example, would allow only files below to be copied using

Restrictions
       This  server  is  known	only  to  be self consistent, that is, it operates with the user TFTP program, Because of the unreliability of the
       transport protocol (UDP) and the scarcity of TFTP implementations, it is uncertain whether it really works.

       The search permissions of the directories leading to the files accessed are not checked.
