I just bought a PCI card, which contains 1 parallel interface (DB25)
and 2 serial interfaces (DB9).
My plan is to program a PIC-controller, so I took the chance that I
could find a driver for Mac OS X, even though card-package didn't
tell me anything else than support for 7 different Windows platforms
(?!??)
Now, I took a look at Apple System Profiler, and I noticed
"Apple16X50Serial.kext 1.0.5 27 Jul 2002 10:42 PM (No description)
It appears that I'm in luck (if my guess is right), and I got the
driver.
It seems to be a standard UART. Google for UART and 16550. You find
lots of information about the chip.
Yep, the back of the box says what's in it. =)
"Netmos 9835 chipset. Serial transmission rate up to 1MByte/sec. 2xHigh
speed 16550 UART. 1x ECP/EPP Parallel port. Support Standard Parallel
Port (SPP), (EPP) & (ECP)."
Now.. When looking in the Network panel in System Preferences, I
didn't see the new hardware, so I believe I have to do something
myself as well.
(In fact, this is good news, because I don't like that anyone else is
taking over my port. ;))
It's serial device, not a network device.
:) True, however, it could be seen as "a possibility for adding a
modem", so it could have been available in the modem-lists.
-So my question is: Where do I go from here ?
If it's of any help, the brand of the card is "Sandberg"; it's a
danish manufacturer, so you probably didn't hear about them yet.
IOKit is your friend. Read about it.
You can get the sources for Apple16X50Serial from the Apple Darwin
site. Maybe IOSerialfamily is also interesting.
I got the sources now, but I noticed that the kext that comes with
Jaguar is version 1.0.5, and the version of the sources are 1.0.0.
-There might be some important fixes in there, that I'd need to
proceed, however I'll try and see if I can understand what's going on.
;)
I'm planning on releasing the PIC programmer for free with source,
when I'
m done, just so that other people can enjoy it. ;)
Nice to hear. Please drop a mail if it is ready.
Indeed, I'll post the URL if I can get it working. =)
Love,
Jens
