Trouble getting all my com-ports (ttyS*)
I just installed CentOS 5.1 on a Dell Vostro 200 (Intel G33) which has a Sunix PCI-Express (x1) 8-port RS-232 card installed. For me it looks like only 4 ports are recognized, but I'm not sure if it's even working with those 4. >From 'dmesg' I see this: ... Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled ACPI: PCI Interrupt 0000:04:00.0[A] -> GSI 19

IVT SCD serial port help
guys, A bit off topic here, but since this issue already has a history here: serial connection to the SCD, the never ending story ... - the intel D945GSEJT mainboard (ICH7) has two serial ports with onboard connectors which require a ribon cable to the external DB9 connectors in the case. I tested 5 cables, but none works. whereas I'm not sure if it is a cable problem. this is what dmesg

KVM virtual guest can not use serial port
I hope this is not to far off topic. I have a Windows 2003 guest on a CentOS 5.5 KVM host. I need to use the serial port on the win2003 guest for the application it is serving. I have no idea what needs to be done but it looks like the linux host is trying to use the serial port as the priamary console but I don't really understand what that is or where it is configured. What I need is for

Need help configuring additional serial ports
I installed a 2 port serial PCI card on a system running CentOS 4.3, but I can't get the additional serial ports to work. The card I used is from StarTech (http://www.startech.com/Product/ItemDetail.aspx? productid=PCI2S550&c=US). When it is detected by kudzu, it shows up as a "NetMos Technologies PCI 9835 Multi I/O Controller". I've included the output of

NUT with Cyber Power 700 AVR
I recently purchased a Cyber Power 700 AVR UPS. I installed it just fine and wanted to install NUT to monitor the unit. I searched the mailing list and found a similar post.

Serial port fun: CentOS 4.8 (32-bit) vs. CentOS 5.4 (64-bit)
I am in the process of migrating from running CentOS 4.8 (32-bit) to CentOS 5.4 (64-bit) on my AMD Sempron(tm) Processor LE-1300 system (it is running CentOS 4.8 32-bit because the disk images are from a previous PIII system), and things are 'interesting' WRT how the Lava Computer mfg Inc Quattro-PCI card is being handled. lspci (on CentOS 4.8 32-bit) yields: 01:0a.0 Serial controller:

COPILOT Glucose Meter COM problem
I am a 62 year old beginner in Ubuntu. Thanks for any help, guidance, suggestions on this problem! I have used commands like the following to be certain that I have an active com port: dmesg | grep ttyS rm com1 ln -s /dev/ttyS0 com1 So I suspect the solution lies somewhere in WINE. If all else fails I will get a USB to SERIAL converter cable and try that. My wife has an Abbott Labs Freestyle

Setting up a pci passthrough device
I have been investigating pci pass-through for virtualized guests and the documentation I have found seems to me to lack a certain consistency in its example. This may be due to my not understanding what it is trying to inform me. What I wish to do is to configure a pci multi-port serial i/o card for use by a single virtual host. I start by running lspci -v on the host to identify the serial

How do I configure additional serial ports?
I have installed two 4-port serial cards (http://www.startech.com/ Product/ItemDetail.aspx?productid=PCI4S550&c=US) on a CentOS 4.4 system. The hardware appears to be recognized correctly, as kudzu added 2 entries to /etc/sysconfig/hwconf and lscpi shows both cards (output of lspci -vv for both cards included at the end of this email): # lspci 00:00.0 Host bridge: Intel Corporation
