ttcp also has an option to take the data it sends from a file. Using

file. In all the other cases it flashes continuously.


Since there are a number of ttcp out there, could you please
provide a pointer to the ttcp you are using?  Do you know
if it uses sendfile() or just read() and then send() to send
from a file?
