Hi,
Great Info, why dont you send it to freebsd-doc@FreeBSD.org in order to
get it in to the Handbook.
A quote from the Handbook web page:
If you are interested in helping with this project, send email to the
FreeBSD documentation project mailing list <freebsd-doc@FreeBSD.org>.
Greetings...
Ales

> SYSTEM:
>
> FreeBSD 3.2-RELEASE
> Cyclom 8Yo+ IDE multiport serial card
> Wyse 60 terminal connected on /dev/ttyc00 (Port 1 on the
> Cyclom card)
>
>
> SYNOPSIS:
>
> If your users can live without X-Windows, adding terminals to your
> FreeBSD system is an affordable way to add users without building a
> LAN.
>
> After reconfiguring and rebuilding the kernel, I installed the Cyclom
> card using default settings. I followed the steps in the FreeBSD
> Handbook (12.4.3.3. Configuring the cy driver) for configuring the cy
> driver except for one major exception -- Port 1 on the Cyclom card is
> ttyc00, not ttyc0. I asked the freebsd-questions mailing list about
> how to properly cable a terminal room. The responses I got led me to
> discover the Yost Serial Device Wiring Standard
> (http://yost.com/computers/RJ45-serial/index.html). I assembled the
> cabling and tools to follow this standard and then connected a port on
> the Cyclom card to a Wyse terminal accordingly. The /etc/ttys file was
> then edited and the Wyse terminal was configured for vt100 terminal
> behavior.
>
>
> VENDORS:
>
> The list of vendors I used is listed below. All of these vendors sold
> me good products in a prompt and professional manner.
>
> I purchased the Cyclades Cyclom 8-Yo+ ISA (8-port) multiport serial
> card from www.sellcom.com.
>
> I purchased a Wyse 60 terminal from an Ebay auction. (The seller was
> Midwest Computer Brokers in Iowa.)
>
> For cabling between the Cyclom 8-Yo and the Wyse 60 terminal, I chose
> to follow the Yost Serial Device Wiring Standard
> (http://yost.com/computers/RJ45-serial/index.html).
>
> I purchased a Paladin PC Cable-Check PC cable tester from the Yahoo
> store. (The seller was www.web-tronics.com.)
>
> I purchased RJ45 plugs, an RJ45 crimp tool and Cat 5 cable from
> www.appleseedelectronics.com.
>
> I purchased RJ45 F to DB25 M adapters from www.pccables.com.
>
> I purchased DB25 F-to-F gender changers from www.stonecomputer.com.
>
> I special-ordered AMP Half Tap Filled Tel-Splice Connectors (AMP P/N
> 553017-2) and the Tel-Splice Crimp Tool (AMP P/N 231839-1) from
> www.newark.com.

> PROCEDURE:
>
> Kernel Configuration:
>
> I checked dmesg to see if there were other devices using IRQ 10 or
> memory addresses 0xd4000-0xd5FFF, which are the defaults in the kernel
> config file line for the Cyclom card (found in /sys/i386/conf/LINT and
> shown below). I did not find any, so I left the IRQ and memory
> location specified in the kernel config line alone.
>
> I copied the following line from /sys/i386/conf/LINT into my local
> kernel config file, also in /sys/i386/conf.
>
> # Cyclades multi-port serial card (Cyclades 8-Yo+)
> device cy0 at isa? tty irq 10 iomem 0xd4000 iosiz 0x2000
>
> I confirmed in the Cyclom Y User's Guide pp.23-24 that the default dip
> switch settings corresponded to the IO and memory parameters specified
> in the kernel config. They did.
>
> I then rebuilt the kernel according to the FreeBSD Handbook (5.2.
> Building and Installing a Custom Kernel).
>
> Cyclom Card Installation:
>
> I then shut down the machine and installed the Cyclom 8-Yo+ card in an
> available ISA slot without changing the dip switches. After rebooting
> the system, I saw in dmesg that the kernel had properly detected the
> Cyclom card:
>
> cy0 irq 10 maddr 0xd4000 msize 8192 on isa
>
> (8192 = 0x2000, so the kernel config line does indeed match the dmesg
> output.)

> Though I did not encounter an IRQ conflict or IO memory conflict, I
> did note that the FreeBSD mailing list archive does contain articles
> about what specifically some people did to remedy such conflicts.

> Serial Cabling:
>
> My terminals can be up to 80 feet away from the server. I posted a
> question to the freebsd-questions mailing list asking how real
> terminal rooms are wired. I received some helpful hints which led me
> to the Yost Serial Device Wiring Standard
> (http://yost.com/computers/RJ45-serial/index.html). Instead of using
> different kinds of cables for various serial communications
> configurations, this standard always uses the same cable between any
> two serial devices (DCE or DTE). The difference between DCE and DTE is
> handled by constructing one custom adapter for DCE-s and another for
> DTE-s.
>
> The cables I used were standard CAT5 cables (I had to be mindful of
> how wires of a twisted pair were assigned to RJ45 plug pins, however.
> The standard specifies what to do.) I constructed the cables using
> CAT5 cables, RJ45 plugs, an RJ45 crimp tool and the standard.
>
> The custom adapters were DB25 M to RJ45 F adapters, specially wired to
> be either for DTE or for DCE and to conform to the standard. Instead
> of soldering wires 4 and 5 of the RJ45 end together, I chose to splice
> them using AMP Half Tap Filled Tel-Splice Connectors (AMP P/N
> 553017-2). (The corresponding crimp tool is the Tel-Splice Crimp Tool
> (AMP P/N 231839-1).) A Cyclom serial port and a Wyse 60 terminal are
> both DTE-s, so I made two Yost DTE adapters and plugged one into Port
> 1 of the serial card (with the help of a DB25 F-to-F gender changer)
> and the other into the MODEM port on the Wyse 60 terminal.
