[comp.protocols.tcp-ip] Did BSD4.3 implemented TCP send

TAYBENGH@NUSDISCS.BITNET (08/26/90)

        Did BSD4.3 implementation of TCP send as a synchoronous send,
i.e. the sender (application process) is un-block only after the message
is sent and acknowledged by the receiver?? If it is not, when the sender
is un-block? After the message has been copied to the kernel buffer or
after the kernel is able to push the message out and before receive ACK
from the receiver.
        Please send the response to me directly. I will summarize if there
is enough interest.
        Thanks
