I tried to find information on this but it seems a bit difficult...
Since I have Lazarus installed in my Win7 PC it would be good to know
where in the installation I might find the units for this component.
A search from the top of Lazarus finds a number of files with socket
in their names but no ssocket file at all.
The sockets.pas file I found indicates that it is for OS/2 only
I also found a wiki page http://wiki.freepascal.org/Sockets where some
info could be gleaned.
But I am worried that this component actually is TEXT oriented such
that it strips off/adds line endings to whatever is sent/received...
Could you confirm that the TSocketClient can actually handle raw
binary data such taht one can send/receive a binary file over the TCP
If tha is the case then it might just be what I need to implement my
simple serial port interface via TCP/IP.
