netttyd is the Inter-CPU mobile modem Net TTY server daemon on early 6490 Puma6 ATOM firmware.

Background: Up to 6490 fw 6.66 FRITZ!OS was nearly completely running on ARM, like in ARM-only 63xx Puma5 models.
The ATOM Intel added was nearly unused. Early Intel Puma6 SDK named it an application processor and did not use it at all.
Later AVM ported FRITZ!OS completely to ATOM, the ARM core is only used for the DOCSIS modem since then.

However, the USB-Host is connected to the ATOM, which has way better CPU performance than the ARM.
That is why AVM implemented all NAS and USB-Host functionality on the ATOM on early 6490 firmware.

This covers printserv and ftpd being proxied by tcpproxyd on ARM, tcpproxy_ctl on ATOM controling which ports.
The NAS webserver and the management of all USB related services was provided by nas_ctlmgr.
Since tcpproxyd does not support SSL nas_ctlmgr ran on a separate IP, which resolved from fritz.nas.
Stick+Surf is also splitted into avmstickandsurf.part1 on ARM and avmstickandsurf.part2 on ATOM, see avmstickandsurf.
For UMTS modems netttyd on ATOM multiplexes the TTY devices for netttym.ko on the ARM side.

The network on the ATOM on early 6490 firmware is managed by multid2.
IPv4 and IPv6 network addresses of the respective other side are gathered by avmipc_state.
Some ATOM ressources are mounted on the ARM side using nfs4.
For network throughput tests there's the remote controllable speedtestd on ATOM.
