Well, here's the read-only shell (rosh) that I've been working on. It's functional but still quite rough. My primary intention of posting it at this time is such that people have an easy way to demonstrate to themselves that the library calls I made work. This should apply as a patch to the head of the "dir" branch and the patch for c_cflag/c_lflag. The patch is only

I am about to retire my Sun Solaris workstation and replace it with a Intel box (A Dell Inspiron 530) running Ubuntu. My UPS (an APC SmartUPS2200) only has a serial port for communicating with its controlling host. The Sun has a serial port, but the Dell doesn't. So ... what kind of serial port should I get? I don't really want to waste a precious PCI slot on a serial card (unless I can

I've already read through bug 11811 (http://bugs.winehq.org/show_bug.cgi?id=11811) so I know a patch was offered about two years ago for Wine automatically recognizing the com* symlinks in ~/.wine/dosdevices. Is there any hope that this will be functional soon? I am trying a utility that needs to access the serial ports but there are none shown available in its ports dialog. I do have

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is it possible to run wine with more than 4 serial ports? Looking through the source I seem to see a hard limit of MAX_PORTS=9, I would like something more on the order of 36 serial ports. I need to run multiple apps with a multi-port serial board, and I am hoping to do it though wine. When I try to set a com port of COM6 in my .wine/config file I get

Hi all: My question is concerning the default number of serial ports compiled into the standard CentOS 4.x kernel. It looks like the default is 8, is that correct, and is there a simple way to raise the default that without needing to recompile the kernel? I looked though the /proc directories and I do not see anything there. I have two 8 port serial cards, which bring my total serial

Hi all, I hope this is possible. I have a server, with a network switch attached to the serial port, and I want to rescan the serial port (/dev/tty) to see if it picks it up? I'd prefer not to reboot the server if at all possible. dmesg reports ttyS0 as the active port: [root at zabackup01 ~]# dmesg |grep tty Bootdata ok (command line is ro root=/dev/System/root rhgb quiet xencons=tty6)

Hello, It's a bit off topic, but I'm hoping someone has seen this before. I'm running a couple of headless boxes, one is 4.7 release, the other is 4.8 release. Both have the same issue with newsyslog when I've got the serial port enabled for console management. (-h in boot.conf and a getty running on cuaa0 after the boot process) Logrotate tries to send an HUP to syslogd, but

I sent this out about a week or so ago, but I have heard nothing. I am *thinking* it is a SELINUX problem, but I cannot figure out what. The SELINUX settings for both machines are *exactly* the same (the stock defaults for a standard CentOS 6 install). The *only* difference is that the desktop (sauron) has a few VMs setup (under KVM) and the laptop (gollum) does not. The desktop has an AMD

I have been struggling with setting up two serial ports on an HP/Compaq D512S (Intel P4) under CentOS-5. I am not at all sure why these things were not auto-configured when I initially installed the CentOS system from CDs but they were not. I have found various resources on the web and from them uncovered the setserial utility. What I need from somebody is guidance on how to use this utility to

Unfortunately, many cheap ones don't or have implementation flaws (the Sweex 1000 for instance, which calculates the CRC in the wrong way). In fact, there are a fair number of UPSes in the list of

Hello, (Not sure if this would be better suited for libvir-list, but here it goes!) I filed a bug last week regarding the way in which libvirt assigns addresses to virtio-serial ports. https://bugzilla.redhat.com/show_bug.cgi?id=1042505 To summarize, adding more than 31 ports causes problems because libvirt assigns them all to a single controller, which has a max of 31 (or less if the

I have a small based atom machine. There are four serial ports on the machine. dmesg | grep tty shows 0, 1, 2 and 3. 2 and 3 are on interrupt 10 -and they worked. going into the BIOS COM ports 0 and 1 are also on IRQ 10 and not the standard 3,4. BIOS cannot set anything but IRQ 10, 11 for serial ports. Odd... So COM 0 and 1 dont work right away... I had to put this in the boot script.

Both naming schemes are correct, depending on the *type* of USB to serial converter. The difference comes down to a low-level USB implementation detail which I?ve never bothered to commit to long-term memory.
