I am running MacMinix on a IIci 4/105 with system 6.0.7. I find that Minix takes over the serial ports when I boot it and I am unable to sustain my network or modem connections. I understand that it is good for Minix to be able to access these serial ports but is there a way to disable Minix from requesting the ports so I can do serial IO with another multifinder process? BTW: the result of accessing the serial ports when minix is active is a hard crash on my system. Thanks for any suggestions: Robert Todd Worrall CS Undergrad @ The Univer$ity of Delaware 1106 Christiana West Tower, Newark, DE. 19717 worrall@freezer.it.udel.edu kb2ggs@wb0jjx.ampr.org

The serial lines are opened with OpenDriver calls, which should fail when the port is already in use by another application (at least this is the way I read the documentation), and a little message should occur in the console window saying the opendriver failed. Now this seems to work when I specifiy that appletalk is being used on one of the ports (i.e., MINIX wont use that port and I get a little message). However, when I started Macintosh Kermit first, and then started MINIX, I didn't get a message, so either 1) I misunderstood the rules for using the ports, or 2) some other apps aren't following the rules. Probably #1. As to your problem, in the short term you could turn on appletalk on the port you want to use, then start minix, then turn appletalk off and start your serial line app (can you say hack?). A better solution is to rebuild kernel with NR_RS_LINES == 0. An even better solution would probably be to eventually put it in the configuration dialog box. Joe Pickert
