Re: [time-nuts] Needed: The Real Serial USB Fix
For serial to Ethernet I use ser2net [1] on cheap wireless routers using the serial port pads on the board and a Beaglebone. The application I use (u-blox u-center) can use TCP connections, if you require a real COM port on Windows com0com and com2tcp [2] should work. ser2net sends one TCP packet per character received on the serial port, this may be desirable (when you need the lowest latency) or not (when you want to reduce packet overhead) [1] http://ser2net.sourceforge.net/ [2] http://com0com.sourceforge.net/ On Sun, Jan 27, 2013 at 9:47 PM, Stan, W1LE stanw...@verizon.net wrote: Hello The Net: Yes, I have had the mouse problem, but the more serious issue is when I run multiple (3) instances of Lady Heather (latest version at KE5FX) and after awhile none of the times agree and the problem only gets worse with time.

Re: [time-nuts] Needed: The Real Serial USB Fix
If it were me, I remove the LCD display. I don't see a need when everyone today has a phone. the little AVR chip can bit-bang a UDP packet once per second and put it on your wifi router. That cuts the parts cost by 1/3rd and the display will be where you can see it, on the phone or computer. There are still a few of us who don't have cell phones. :( I split the problem into two areas: Collecting the data Displaying it If I'm collecting data, I want to be able to look back over hours, days, months, or even years. That means I probably want to backup/archive it too. 100 characters of text every 10 seconds is under a megabyte per day. That's small relative to modern disks, medium relative to thumb drives or SD cards and small to medium relative to RAM (or ramdisk). [I generally chop things up into a file per day.] So far, I've always had a handy Linux box running 24x7 when I wanted to collect data, so I've never tried to use a smaller system. Since the data is collected on a real system, it's easy to display it any way I like. I won't be surprised if a project comes along where I want something like a small uP to grab careful timing data. Until then, I'll keep collecting my data on a real PC. Does anybody have data on lifetime of Thumb/SD cards if you flush a log file every 10 seconds? What type of file systems are supported with whatever OS comes with small uPs? Is there any work on flash-friendly file systems for append-only log files? A year or 3 ago, I did some work on logging to ramdisk and occasionally copying to hard disk. The idea was that the hard disk would be spun-down most of the time, saving a lot of power. It didn't save much so I bailed on that project. I assume that means the power to keep the disk spinning is low relative to the power to keep the electronics going. Maybe I just botched the experiment. flushing the file after each line is the simple way to make (mostly) sure that your data gets to disk in case the system crashes, but it turns into several disk writes each line. That's no big deal for a lightly loaded hard drive but gets interesting in terms of total writes to flash drives. You could, of course, fix the code to only do the flush once every N minutes, or only when something interesting happens... -- These are my opinions.

Re: [time-nuts] Needed: The Real Serial USB Fix
OK I may be late to the game here. Using a great device to solve my rs232 port problems. Its a did TS serial poer server. They make them in 16 ports and smaller. Essentially it translates the ports to ethernet and everything I have can then use the rs232 devices. The ports stay put unlike USB thats been a pain actually. Multiple workstations and such can access the ports. They can translate say port 16 so that it looks like com3 First 16 port was free. The 8 ports cost a wopping $5. Nobody knows what these things are so no value. I didn't till I stumbled into 1at work that was getting tossed and the light bulb lit up.

There are some well documented issues with timing and USB that have been rehashed here a few times.

Sure, the timing isn't really , really predictable (8kHz frame rate and all that).. but assuming you're just controlling something where you need 10s or 100s of millisecond timing and shoving data back and forth..

Re: [time-nuts] Needed: The Real Serial USB Fix
I use a Digi serial to ethernet terminal server for various serial devices. You put the client software on your PC and the terminal server ports show up as COM ports on the PC. This keeps the physical COM ports free for any critical timing applications. Drivers are available for Windows 98 to Win7, Debian, Ubuntu, Fedora, Solaris, AIX, HPUX, etc. Seems like a reasonable list of operating systems. Am I missing something?

I'd have gone to that long ago if I could point any bit if software at a serial port that was actually on a terminal server out on the ip fabric.

Re: [time-nuts] Needed: The Real Serial USB Fix
It came down to startup issues. If every fifth time the system was turned on it wouldn't initialize properly and not see an airflow or whatever sensor, it required the calling of a tech from the test group to come over and get it going. We run Labview but it was always a Windows problem as the devices wouldn't show up in Device Manager.

Re: [time-nuts] Needed: The Real Serial USB Fix
Hi We've had better luck with the FTDI based parts than with the other USB serial gizmos. Even they do drop out every so often. With the modern drivers it's a lot more rare than it once was. With 32 ports on a system and several systems it's a once or twice a year sort of thing now. Bob On Jan 27, 2013, at 2:28 PM, Peter Gottlieb n...@verizon.net wrote: It came down to startup issues.

Re: [time-nuts] Needed: The Real Serial USB Fix
What I would really like in Windows is a way to lock the configuration and make it more of an appliance which always worked the same way. That way a small board talking to a Thunderbolt would always start up and just run. I suppose I need to get away from Windows and climb the Linux learning curve.
