I installed Board Master a software that control a CNC machine to produce PCB (Printed Circuit Board). The software install flawlessly but to check if it works I need RS232 working to control CNC machine. I tried to set connection parameters in Board Master choosing COM1 (the only available) but CNC machine don't move and software keep asking for switching machine on. Of course software and CNC works in Windows XP. 1) is RS232 working on Wine ? 2) if yes how can...

Hi there Does any one of you know something about R and an implemented RS232-Interface? Are there any packages? Or is it possible to write an extensions or something like that in C/C++ ? The problem is that i should handle the information from a measuring device via the RS232-Interface (probably you know LabVIEW, which provides this functionality). These informations shoul...

Hello all. This is a question that I should be able to answer, but the old grey cells aren't working. My Google-Fu must not be up to snuff, either. I have a MOXA IP-RS232 converter that I'm going to be using over an RF WAN and I need to confirm the actual data rate that I'll be able to achieve. I have the drivers loaded (/dev/ttyr00) and a loopback plug on the end of the device. I am able to confirm that it works fine with minicom, but I'd like to be a...

.... But... the problem is, my macbook has not the RS-232 port. So I bought a RS-232 to USB adapter. I've installed the correct "drive" to use that. I've tried that in windows, and ok, the azloader was able to send data trhoutgh the "com 3 port" (that's where the driver rs232-usb is installed). But my macbook couldn't. I believe that wine runs the azloader right, but it's not able to use thet rs232-usb mac's drive! I haven't installed the driver for windows with wine. What to do? install the rs232-usb windows driver using wine? what eles? install windows...

Hi all, Is there a method in centos where a program can be started that listens on a given IP port and when something connects it will transfer data from the RS232 port to the IP port. reads and writes of course. Trying not to reinvent the wheel if I dont have to... Thanks, Jerry

Hello Does anybody know if it's possible to monitor a Powercom EBk 500 (RS232)? the trick is that I am using a raspberry pi, it does not have RS232 so I connected a keyspan RS232 to USB adapter, but so far I can?t make this work.

...ber 19, 2006 7:28:30 AM Subject: Win32 OVERLAPPING IO Hi Daniel, My name is James Tucker, I''ve been hacking in Ruby for only a few months now, however am an experienced general programmer in a wide variety of languages. My current focus is on a new development project involving an RS232 data protocol handler, which up until now I have programmed in ruby. We have a small problem with the ruby platform for this issue however, and it is related to several factors: - Ruby threads are green threads, IO blocks block all threads. - RS232 Comms on Windows using the Windows::Fi...

I've several USB <-> RS-232 dongles around. As well as a few embedded devices. They all "Just Work (tm)" on Redhat, CentOS, Fedora, Debian, Raspian and Kali. Knock on wood - never had a problem using any of them. As the drivers are part of the kernel, I'd expect any distro using a recent kernel to do well.

Hello list! I can't seem to get this running via RS232 monitoring; I've been told that NUT won't support serial connections, and find this hard to verify. Does anyone else have this running on the SU10KRT3U via RS232? If so, what driver did you use? I'm getting no satisfaction from the "tripplite" driver; upon upsdrvctl start, I g...

...t Linux distros will drop back to a non-hardened filesystem in the future are nil. And that brings me to my third question: 3. Why should we care about 'smart' serial UPSes any more? I've already shown that supporting dumb UPSes is silly under modern conditions. Supporting anything RS232, in particular smart serial UPSes, seems almost as pointless in 2007. USB UPSes are ubiquitous and cheap; when I recently went shopping for a UPS I found a USB-capable unit for $29.99. Belkin no longer manufactures any RS232-only units at all and APC hasn't shipped a new RS232-only design sin...

...VA Pro and PowerMust 600VA USB and the first two of these are listed in the NUT's compatibility page as "full compatible" using the "megatec" driver: in fact they perfectly work. I would like to report that also the third one is compatible using the megatec driver, both via RS232 and via USB port. So I hope it could be inserted in the compatibility page. The only thing that's "strange" is that the driver report a 97.5% battery charge status also if the UPS is at full charge (it's attached to power network by several days without interruption), as you can s...

Hi all I was wondering if one of you kind gentlemen (or ladies) would assist me in finding the data string required to tell my ups to turn on and off. No more no less :) I guess it would be the actual string of an instant command sent down the rs232 port to the ups. I have no programming experience and have done a list search to no avail. Sorry to trouble you with this. I have a lan to rs232 device called a Global Cache gc-100 which can send a data string out the rs232 port (commonly used for home automation). I know how to address the gc...

Ubuntu creates /dev/ttyUSB0 for me when I plug in the usb-to-serial-adapter. I have a symbolic-link to /dev/ttyUSB0 from 'dosdevices/com1'. What is new in 10.04 Ubuntu is that I have to sudo chmod o+r and sudo chmod o+w on /dev/ttyUSB0 every time before I start the app which uses that serial line. ttyUSB0 goes away when I unplug the serial adapter from the USB port or shut down the

Hi Recently i bought a MicroDoWell BP50, and with it followed a USB 2 serial converter. When i plug it into my 2.6.19 kernel, dmesg shows hiddev96: USB HID v1.10 Device [Cyber Power System CPS RS232 USB BRIDGE for UPS] on usb-0000:00:04.2-2 usbcore: registered new interface driver usbhid drivers/usb/input/hid-core.c: v2.6:USB HID core driver So, i figured i should use usbhid-ups, /etc/nut/ups.conf [switch] driver = usbhid-ups port = auto and then i ran the command /lib/nut/usbhid-...
