Very exciting news for collectors of old cellphones:
There's ways again to get data connectivity on devices which don't support GPRS/packet data.
This Nokia Communicator 9110 is running DOS on a AMD x86 CPU and is connected to the internet via a 9600bps CSD call through a private GSM network!
The Osmocom free/open GSM stack gained CSD support over the last months and it now actually works :)
