: Ok, I logged in as root, delete the LCK file and then
: in kermit I tried to set line. I got the error
: "Permission denied". However, it I change the
: permissions on the modem to 666 (owner root, group
: system), I don't receive any errors on set line. But
: if I set speed or connect, it says you must set line
: first.
:
You mean if you "set speed" or "connect" *after* you
SET LINE? That makes no sense. SET LINE opens the
device. Once the device is open, Kermit has a file
descriptor on it, which it can use to change the speed,
do reads and writes, etc. This should be true EVEN IF
some other process has changed the device or lockfile
permissions back to what they were before behind its
back.
