Problems have been reported on operation of serial ports on Mac PowerBooks in the past, especially in connection with MIDI. It may be that your problem is related to that! I am referring here to earlier PowerBooks, not G3s.

It sounds like something else is using the serial port. The most obvious candidate is AppleTalk, if you have it configured to use LocalTalk. But it could also be OMS or the MIDI manager or a terminal enumlator.
You could try (a) turning off AppleTalk and (b) booting with extensions off.
Just to report: I just tried turning off EVERY EXTENSION (including Fax -- thanks, Pat for the suggestion!) except CFM-68K. Same error -- primitive failure. I also tried a variant on Joshua's suggestion -- I hardcoded the selection of the portnumber to be a "1" and a "2", rather than the default "0". Same thing.
Curious.
