Abstract:
|
|
|
|
This file implements the client-to-server flow
|
|
of data for remote server. The data is the keyboard
|
|
or piped input that the client received and sent
|
|
over the wire to us, bracketed by BEGINMARK and ENDMARK
|
|
bytes so we can display nice attribution comments in
|
|
brackets next to input lines.
