I've reached the point where my Cyclades Cyclom-Z driver is stable, and is actually doing quite well (we use it for modem testing here at Cisco in several groups). For those who don't know, the Zs come in one of three forms: 8Zo (V1) - 8 ports per card to 460K per port 8Zo (V2) - 8 ports per card to 920K per port 8Ze - up to 64 ports per card to 920K per port So far, I've run 32 ports (4x8Zo V1) in a Pentium Pro 200 using about 30% of the CPU at 115200 baud (this includes running PPP with FTP sessions saturating all of the links). As you can see, the boards are quite nice. Anyhow, I promised Cyclades that once the driver was stable, I'd offer it up the FreeBSD core for inclusion in to the standard operating system. I've uploaded the driver to ftp.freebsd.org in /pub/FreeBSD/incoming. The archive name is cz-0.N.tgz. It includes everything needed to drop it in to the kernel source, has a RELNOTES file, a makedev program (my shell scripting skills haven't been used for a couple of years, so I wrote it in C. Someone may want to translate it back), the firmware, headers, etc. The only thing that wasn't included prefab was the change to files.i386 in the conf directory (simply because it was straight forward enough). If someone could take a look at it, and either commit it, or reject it with comments on "whats wrong" (don't be too harsh, this is my first "real" Unix driver, and you don't want to scare me off from doing more :) ), and how you'd like it fixed, I'd appreciate it. I also expect to continue to support the driver, and make some changes (for instance, I'll be trying to add DMA capabilities, so the board can move the data directly in to kernel buffers, so the kernel can avoid PCI bus arbitration on an interrupt/poll), so comments, suggestions, and diffs are very much welcome. -Brian
