mknod device nnumbers (again)

First off, thanks to all the people who gave me info for the rk? and rrk? devices. That now works. I now come to the question of tty devices. On v5 and v6, the single terminal device which is set up is /dev/tty8 (c 0 0). This suggests to me that the system is build with a DZ11 (or similar) as tty0 to tty7. Am I correct in this assumption? My system has a pair of DL11s, and one of them works happily as tty8. I'd like to get the second interface up and running. I also have a DZ11, if that is any help. (The second DL11 is set up at present and works with RT11 using the CONSOL.MAC mechanism to switch ttys. I can't remember the CSR/VEC, but it is the RT11 default for a second DL11). Question is: ------------ What is the device numbering (major/minor) for a second DL11? (and what CSR/VEC should it have?)? Or need I rebuild the system for support of a second DL11? Second, is the DZ11 supported by default, and, if so, what CSR/VEC should I set, and what are the device major and minor numbers? Cheers once again, Bob. -- ---------------------------------------------------------------------------- Robert Manners Osney Laboratory rjm(a)swift.eng.ox.ac.uk Dept of Engineering Science University of Oxford 01865 246561 x 162 Try: http://swift.eng.ox.ac.uk Linux - the only choice "The comfort you've demanded is now mandatory" - Jello Biafra ----------------------------------------------------------------------------
