I'm trying to get a handle on using the modem via perl, and find that perl's open() seems to hang or block on accessing the modem. If I run minicom in another xterm, however, then open() works (my test application is not honoring the lock file, of course). I've tried to find information on the lock file protocol, but with limited success, and the best I've come up with is by looking at the minicom source which deals with the modem lock file. Both ppp and minicom use the same lock file format, putting the process id in the file /var/lock/LCK..modem. I don't think this is SuSE-specific, but could someone point me at some documentation on the lock file protocol? Thanks for any help. -- Ken Irving -- jkirving@mosquitonet.com Trident Software -- <A HREF="http://www.mosquitonet.com/~jkirving/trident"><A HREF="http://www.mosquitonet.com/~jkirving/trident</A">http://www.mosquitonet.com/~jkirving/trident</A</A>> - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e Check out the SuSE-FAQ at <A HREF="http://www.suse.com/Support/Doku/FAQ/"><A HREF="http://www.suse.com/Support/Doku/FAQ/</A">http://www.suse.com/Support/Doku/FAQ/</A</A>> and the archiv at <A HREF="http://www.suse.com/Mailinglists/suse-linux-e/index.html"><A HREF="http://www.suse.com/Mailinglists/suse-linux-e/index.html</A">http://www.suse.com/Mailinglists/suse-linux-e/index.html</A</A>>
