I'm having a problem with the login program hanging when getty passes control to it. To eliminate any extraneous device influences, I've looped sio0 to sio1 using a null modem cable. If I use tip on both serial ports simultaneously, everything communicates fine. When I enable getty on one of the ports and tip to it from the other port, getty accepts a login name, forks login, which gets stuck. Eventually login times out and getty restarts. Here's what it looks like: ======================================================================== Running tip from cuaa0: root@infoserver.ee.siue.edu# tip slink connected FreeBSD (infoserver.ee.siue.edu) (ttyd1) login: bnoble Password:Login timed out after 300 seconds FreeBSD (infoserver.ee.siue.edu) (ttyd1) login: ======================================================================== What's happening on ttyd1: root@infoserver.ee.siue.edu# ps auxwtd1 USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 23088 0.0 1.1 156 520 d1 Is+ 10:22AM 0:00.02 /usr/libexec/getty std.38400 ttyd1 root@infoserver.ee.siue.edu# !p ps auxwtd1 USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 23088 0.1 1.4 220 668 d1 S<s+ 10:22AM 0:00.06 login -p bnoble root@infoserver.ee.siue.edu# !p ps auxwtd1 USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 23088 0.0 1.4 220 668 d1 I<s+ 10:22AM 0:00.06 login -p bnoble I've tested this on a 686 running 2.1.6 and 2.2 and also on a 586 running 2.1.5. Both system do exactly the samething. Does anyone have any insight into this problem?
