Then you generally lose the value of the hardware networking stack acceleration.
Why do you need URG flag? What are the possible scenarios?

I was looking at implementing a TELNET system on a microcontroller and to be fully compliant I need to be able to send TCP packets with the URG flag in order to implement the Synch system.
Annoyingly, there doesn’t seem to be any alternative to the URG flag despite modern standards suggesting it no longer be used.

Ok, I see. Afraid there’s no such functionality within the chip. The workaround could be withholding putting further data into the TX buffer (its size is relatively small - by default 2kB) and inject telnet control code in between current and further data.
