He's probably talking about ttcp, not T/TCP. As in:
NAME
ttcp - test TCP and UDP performance
SYNOPSIS
ttcp -t [-lbuflen] [-s] [-nnumbufs] [-pport] [-u] [-D]
[-L] [-Aalign] [-Ooffset] [-v] host [<in]
ttcp -r [-lbuflen] [-s] [-pport] [-B] [-Aalign] [-Ooffset]
[-u] [-v] [>out]
DESCRIPTION
Ttcp times the transmission and reception of data between
two systems using the UDP or TCP protocols. It differs
from common "blast" tests, which tend to measure the
remote inetd as much as the network performance, and which
usually do not allow measurements at the remote end of a
UDP transmission.
It's extremely useful.
