[edit] NetMos Technology PCI 9835 Multi-I/O Controller (rev 01)

• This is a 2 serial, 1 parallel port PCI I/O card. While it works with Linux, it does not work “out of the box”. You have to do some manual configuration. The CD that comes with the card does have Linux install instructions. But if you are running the 2.6.x kernel, all you have to do is add parport_serial to /etc/modeprobe.preload, and the ports are configured for you. I did not try 2.4.x kernels with it.
• On my system, the two serial ports became ttyS4 and ttyS5. The parallel port became lp1. This may be different on your system. The logs will show the port assignments. If you have a fairly standard system, you will probably get the same results. I have the usual 2 serial and 1 parallel port on the mother board. So they get ttyS0, ttyS1, and lp0. I don't have anything on ttyS2 and ttyS3.
• Tested with 10.1 and LE2005.

[edit] SIIG CyberParallel Dual: Two IEEE 1284 EPP/ECP parallel ports

• This is a 2 parallel port PCI I/O card. It is automaticly detected by the kernel, so no configuration is necessary. If you already have lp0, then the card will be lp1 and lp2.
• Tested with 10.1.
