Hello,
I have a question about the way serial ports are detected. Since I started using udev last year I noticed 32 ttySxx nodes in my /dev directory. I checked dmesg and the serial port driver was detecting 32 ports. Here is the line from dmesg: Serial: 8250/16550 driver $Revision: 1.90 $ 32 ports, IRQ sharing enabled In fact I don't have 32 ports. I have two serial ports on the motherboard, both of which are disabled in the BIOS. I opened a bug in RedHat's bugzilla system and it was promptly closed saying this was unfixable. I was told that the kernel loaded the maximum number of ports supported by the serial port driver. I asked why and I have not received a response. So I ask this mailing list Can the kernel detect the proper number of serial ports or not?
Thanks, Jason
