Hey! I thought I'd let you know I'm currently using DOSEmu/DR-DOS to _replace_ a Concurrent DOS system implementation. Running multiple instances of DOSEmu/DR-DOS on one Linux system is just like running Concurrent DOS, from the standpoint of local file access, file locking, etc... Only now I _remove_ the requirement of separate serial lines, and just use the normal network. No issues with "serial port" access either. It is for an accounting application from RoundTable Software. Normally, RoundTable has been recommending people move away from the Concurrent DOS approach and just put all the files on an SMB share. Of course, the stupid "by default" oplocks optimization that native SMB servers use is trashing everyone's files. I have repeatedly recommended they use Linux/Samba instead, as you can turn off oplocks on a per-share basis. But even better than that is the fact that with DOSEmu and X-Windows (XDOS binary), Linux gives you even a better option! One that works just like Concurrent DOS! Multiple sessions, 100% local access! You just run the multiple sessions on that one Linux box, and pump the X-Windows display to another system (e.g., XDOS -display system1:0, XDOS -display system2:0, etc...). Once I've gotten the system completely switched over, I'm going to document (with diagrams/illustrations) this for the "Linux unfamilar". I've tried explaining it to Roundtable but they don't understand it (as most don't, simply because they are unfamiliar with X-Windows basics). -- Bryan P.S.
