My guess would be one of those things like resmngr grabbing it for use by
the desktop user (like a modem). Perhaps you have desktop gadgets to setup
the modem: remove them. I'm thinking of kinternet and family. Or use Yast
to tell it the modem is at ttyS1 perhaps. If there exists a /dev/modem
link make sure it points somewhere else.
