IE: why not just > use dosemu, with the appropriate BSD kernel support? - We control doscmd, so we can Do It Right. - Doesmu is a festering mess, in typical mongolian-hordes style. Doscmd is relatively tidier, and is amenable to being tidied more. - Doscmd is BSD-licensed, so if someone wanted to use it for their own project (commercial) they could. BSDI are keen to see it maintained too, and I'd like to DTRT by them (they gave us the code in the first place). > Jonathan Please keep the list in touch with your progress, and let me know if you want the latest-latest copy of the userland code and I'll bundle it up (fixes at least one major redirector bug IIRC). -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
