[En-Nut-Discussion] Delphi connection for Nut/OS

[Bogdan Hent]

Hi Ole,

Thank you for answering.
Yes, I mean borland Delphi?
I want to use TCP connection and I want to know if it's possible to connect
using TClientSoket or another component and maintain connection alive
between server and the device. Also, I attached a barcode scanner to device
which scans the barcode and it's supposed to send the code back to server
application.

If you have some examples, it would be great for me!

Thank you,
Bogdan
