I know one of the UK DEC Legacy guys has written some code to support Type "C" SNA controllers. From

https://groups.io/g/declegacy/message/178

" To avoid requiring special hardware on the PC I opted to use a Cisco
router with a WAN interface card (WIC-2T in this case) for the SDLC side
and DLSw protocol for communicating with the PC. This protocol would
normally used between two routers to carry SNA traffic over a WAN. By
following RFC 1795 I was able to implement my own DLSw peer in
comm3705.c. This allows me to transmit SNA packets from VTAM to the 3174
and back again."
