\&\fBbpecho\fR \fIownEndpointId\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBbpecho\fR uses Bundle Protocol to receive application data units
from a remote \fBbpdriver\fR application task.  In response to each
received application data unit it sends back an \*(L"echo\*(R" application data
unit of length 2, the NULL-terminated string \*(L"x\*(R".

\&\fBbpecho\fR terminates upon receiving the \s-1SIGQUIT\s0 signal, i.e., ^C from the
keyboard.
