These are some modifications I've made to comm3705.c to add DLSw support. When used in conjunction with a Cisco router and a WAN card such as WIC-2T it essentially gives an SDLC port that can be accessed over IP. This means that no special hardware is required in the system running Hercules. Also I don't have to worry about the SDLC protocol as that is handled by the router. I just transfer SNA packets between VTAM and the 3174.
I went down this route because I wanted to connect real 3270 terminals to Hercules, however finding a 3174 with Token Ring or Ethernet proved to be very difficult (or expensive). I was able to to get a 3174-91R though so I decided to code my way around the problem :) For the question regarding 515x terminal emulation that should be possible using this setup (in reverse). You can send whatever you want over the DLSw/SDLC link, it doesn't have to be SNA. Matt
