I'm trying to get the 6 port Boca card working on 1.1-RELEASE. I've
built a kernel with COM_MULTIPORT, and can talk to the ports (set up
as sio2-7 above 2 standard ports) but I seem to get delayed output
(apparently always one operation behind). This is for output only,
no getty running and BI_DIRECTIONAL disabled. My guess is the problem
relates to the lack of a "master port" interrupt, and possibly the
interrupt register address. The system does see all the ports when it
boots and reports no problems at that time. I've been through all the
docs I can find, and looked at sio.c in current, which makes references 
to some of these issues (master port) in ways that are different from
the RELEASE sio.c, but I'm not sure I can use the code in current alongside
the RELEASE kernel. The ports work fine if I set them up for unshared 
interrupts as standard COM1 and COM2.
