Re: [Synalist] SynaSer Linux USB crash when set RTS
I bought a GUC232A made by IOGear (with a pl2303 prolific chipset) and that works under both i386 and ARM Linux. It appears that some linux drivers for FTDI and MOSCHIP chipsets have problems. I'm glad that I found something that works, and it also appears that SynaSer and FreePascal work OK. I've read that some IOGear (and other) adapters with the (later) pl2303X chipset aren't compatible with some devices so it is possible that other GUC232A adapters may not work (so be warned). - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ synalist-public mailing list synalist-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/synalist-public

Re: [Synalist] SynaSer Linux USB crash when set RTS
Hi, I have used simular converters before and this sound like a driver issue. I found that the USB-Serial converters from EasySync is the best and when connected to Linux provides a full 'real' serial port without any issues. Simply connect to ttyUSBx and continue from there. Are you able to communicate using Minicom for example?

[Synalist] SynaSer Linux USB crash when set RTS
I've now encountered the same problem with i386 Linux and ARM9 Linux using SynaSer and FreePascal. Thought I'd leave a message here before I spend more time looking into this. Normal (real) serial ports work fine but when using USB to serial adapters the program crashes upon connect unless I comment out these two lines: procedure TBlockSerial.Connect(comport: string); ... RTS := True; DTR := True; With those lines commented out things work but my program crashes if I try to set RTS somewhere in my code. I've encountered the same problem using two different adapters. The adapters have FTDI and MOSCHIP chipsets and both automatically detected and installed in Linux. I need to manually control the RTS line to key a radio so I need to solve this problem soon. The MOSCHIP adapter gets wrong receive data on ARM9 Linux but that is another problem. My connected radio needs 1200 baud and right now I suspect the baud rate is not being correctly set. Thanks in advance for any suggestions. -- Regards, Paul Breneman www.BrenemanLabs.com www.TurboControl.com/TPSupport.htm - TurboPower support links - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ synalist-public mailing list synalist-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/synalist-public
