  • Dosemu is not locking up

    I am not sure if this is causing dosemu to lock up after trying to a bbs door game?

    The suggestions to correct some things are in the WARN lines.

    The line about faulting out might be related to the items listed in the WARN lines, there are some other items listed here in case you run into more issues:
    https://tldp.org/HOWTO/DOSEMU-HOWTO-11.html
    Section 11.1 is a common issue for the Fault, it has to do with suid root permissions on the dosemu executable.

    I fixed this issue by adding exitemu in the batch file. It seems that some of the bbs doors do not like to play nice with dosemu.

    That works too. Although technically, you weren't locking up if that was the case. When the BBS appeared to be locked, it ends up waiting for dosemu to exit. I'm betting you could have typed 'exitemu' into the void and your BBS would have regained control.
    http://wiki.synchro.net/howto:dosemu - see Troubleshooting

    It's been so long since I set dosemu up, I forgot about those 'lockups'.
    Glad you got it figured out.
