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.
