Setserial crash
Hi all, Having successfully installed the modem on my iMac running Mandrake 8, I have been playing around to try and improve the throughput as I've done of various PC's. This involves changing the modem port speed via setserial. Modem detects correctly on access, and dials in on /dev/ttyS0 via a script. On startup: PowerMac Z8530 serial driver version 2.0 tty00 at 0xc385b020 (irq = 15) is a Z8530 ESCC (internal modem) tty01 at 0xc3896000 (irq = 16) is a Z8530 ESCC (IrDA) Using setserial to access: # setserial -a /dev/ttyS0 /dev/ttyS0, Line 0, UART: unknown, Port: 0xc388f020, IRQ: 15 Baud_base: 0, close_delay: 50, divisor: 16 closing_wait: 3000 Flags: spd_normal When I attempt to alter the speed, the programme gives a nasty error and locks the machine up solid. Error as follows: # setserial /dev/ttyS0 spd_hi Oops: kernel access of bad area, sig: 11 error traps TASK = c0d32000[1537] 'setserial' Last syscall: 54 more error traps Obviously not a good sign. Has anyone else had any problems using setserial, and can any suggestions or workarounds be suggested? I've attempted to set a uart and other tricks, but each time I use setserial to change a setting, it locks the computer requiring reboot. Damian.
Modem Detection
Yet another cry for help. It appears that the built-in modem on my Bondi Blue iMac was not detected by the usual automated detection routines. I'm presuming that its one of the devices listed under harddrake as unknown, but that isn't terribly useful to me. I don't mind this so much, as I plan to use the machine as a firewall and NAT machine without X running. However it also appears that the various serial ports don't answer with anything resembling modem activity, or even identified ports (setserial /dev/ttyS0, ttyS1, and /dev/modem all report unknown UART, etc.). My questions are firstly should I expect to see the modem reported as a serial device, and if so, which serial driver has anyone had any success with? The iMac presently loads serial drivers with the following message: Serial driver version 5.05b (2001-05-03) with HUB-6 MANY_PORTS MULTIPORT SHARE_I RQ SERIAL_PCI enabled I'll send the mac unknown elements direct to the harddrake support people. Any hints useful. I have to say that this is more entertaining than the quick and easy install on traditional PC hardware, where most of the glitches are well ironed out. Damian.

I either get a nice looking display but the ADB mouse responds extremely slowly or I get a squished display with odd colors, the images wrap strangely on the screen, but the mouse functions fine. When the mouse is unresponsive, the keyboard also responds poorly (very, very slow). I got the display problem using an early Bondi Blue iMac, with a meager 2MB video display and 32MB of system memory. It appears that the problem stemmed from selecting a video resolution that the machine did not appreciate. Initially I Chose 800x600x32bit, and it gave a screen in grey 1 screen height and 4 screen widths wide. The problem was solved by running DrakConf and setting the video colour level to 16 bit on my particular machine. I also noticed several messages on the first console. The same message kept scrolling by which basically said the default locale was set incorrectly in a gtk module (perl I think?) and it could not find the correct information. I doubt that has anything to do with the problems I have but it could be something to clean up later. I also had this on an initial install after choosing the UK location. I defaulted to US on the next install and the error went away. I didn't not any real problems apart from the error messages though. Damian.
