Hi,
you can read LastError and compare with WSAETIMEDOUT or other (in sswin32.pas
or sslinux.pas).
You can know if port is open with WSAECONNREFUSED (or WSAEADDRNOTAVAIL if ip
address not found)
regards
Emeric

HI All.
I have written a simple TCP client thats running in a
thread.
I want to know what the best way of detecting if the server
is not present is.
I am doing a “repeat until” to read the received data
from the socket. I was looking at the “lasterror” after it does a “socket.
RecvString(1000);” but the last error could be timedout which it is, it timed
out reading the buffer.
However, I really want to “monitor” if the connection is
open or closed.
I was looking at the OnStatus event, but the error in that
is also timedout from the above.
Can anyone suggest a good method/practice to monitor the
connecton?
Thanks, Jeremy
