Hi edoc,

The basic answer to your question is :
puppyserialdetect -u | grep SERIAL

puppyserialdetect is a bit slower than the latest puppyinputdetectFULL, and (puppyserialdetect) may be hazardous to some systems, i.e there are outstanding reports that it freezes some systems on boot, probably by not exiting.

Basically it just scans the kernel info about serial access ports, which is here /proc/tty/driver/serial which might be enough for you?
cat /proc/tty/driver/serial

Attached is source code of latest incarnation.

To detect the serial ports, use puppyinputdetectFULL with -swm command line options. Use -d for debug mode.

Examples:

Thanks!

Really late here tonight and a busy day tomorrow at church ... will try to see how this all works asap and report back.

Thanks again!

In chasing down my serial port challenges I stumbled upon the following URL's, the first is clearly related, the third URL I just wanted to post in case someone knew of a thread where I should move it in case it is of use to someone chasing a relted problem.

This appears to be the driver I need for my USB-Serial-RadioTransceiver project.

This links Puppy & a project requiring the FTDI driver.

Sure would like to get access to my serial port, directly or via USB.

Help, please?

Just a quick observation...we must have installed puppy on well over three hundred computers now, and not once has puppy ever failed to correctly detect the mouse. This has been mostly with 2.15ce and earler versions. I do realise there is an occaisional report of serialdetect failing to detect mice on the forum, and it must happen at some point...but isnt that where a forum comes in?

One of the few things that seem to be a step backward in the new puppy is adding an additional screen to the first setup (xorgwizard?) to confirm the type of mouse. Adding an extra setup screen will lose us more users through decreased useability/complexity than the very few that serialdetect doesnt work for. Perhaps the serialdetect screen should be accessed separately from the xorgwizard with a command like "setmouse"?

That being said, I am glad that more work is being done to improve serialdetect, should it ever fail for me in the future!

I don't have any problems with the mouse, it is access to the serial port for access to/control of external devices e.g. programming a radio scanner or setting up my weather station.

I have the software I need but cannot get recognition of serial/comm ports.

I keep hoping that there is an app out there in the Linux worl that brings up a troubleshooting window, detects the hardware, then walks one through what settings are incorrect to re-establish reliable communications.

I have tried a USB-to-Serial and direct Serial connection but nothing works.

I am also unable to access any USB-based printer from this laptop, local or remote, and presume that the problems have a common denominator. (I had no problems with printers like this under 4.0 and prior.)

WDYT?

I do recall in a prior version, not sure if 4.0 or 4.11, there was a question about checking for Serial devices in the Boot stage.

The idea was to save time by skipping that check. I may have done so.

Is it possible that in the version upgrade that setting was maintained?

Anyone remember where that would have been set and how I might undo it if it has in fact been set, please?
