Tethereal prints to the standard output; by default, that's the terminal
or console window, but if you redirect the output of Tethereal with the
standard UNIX and Windows syntax

	tethereal >file

it'll write to the file named "file".

The packet summary includes the sequence number and ack number only if
you don't dissect anything past the TCP header, so if *that's* what you
want, even for protocols running atop TCP, there's no way to do it in
Tethereal, because there's no command-line option in Tethereal to
disable protocols.

The option is "-R".
