Hi all,

I have a question in regards to tty's vs sockets.  We have an application
where we have multiplexors connect to our unix box via RS-232 to terminal
ports.  Like this:

(20-1)             |-------------|
Mux 1 -------------| tty's       |
Mux 2 -------------|   A 5.2     |
Mux 3 -------------|    box      |
etc.. -------------|             |
                   |-------------|

We have run into the old problem of only being able to recieve X (64?) of
bytes from the mux at a time on our tty port.  What we really want to do
is to be able to send 1K blocks at once.

Now would going to a more modern approach using a sockets (no ptys)based
interface having our multiplexors connected to an ethernet allow larger
transfers of data to the unix box?

Please reply via e-mail.
