lovelylinux · 12-04-2006, 12:44 AM

Hi to all,

I want to get the Product ID, Vendor ID and Manufacturer of the Serial Port Device attached.

I want to get all the information regarding to serial port without using the proc file.

How can I get all the Information ?

Please give the Details.

Any good suggestion is appreciated.

Thanks.

um plug it in and reboot, see if it is detected (dmesg).

Some reading:

AFAIK: there is no way in general. I had this up a while ago when I wanted to find out about an ISA modem. What exactly are you trying to acheive?

Thanks Simon for reply

Actually my task is to detect any Serial Device and get the Vendor ID , Product ID and Manufacturer Name and update my running application.

Please Give me other Details.

Thanks.

Are you refering to devices connected to the serial port or the serial port itself?

In general there isn't a standard protocol for finding information or communicating to a serial device similar to USB devices.

Most MODEMS are AT command compatable and so can be easily identified. I know that serial mice can be probed too but don't know what information can be determined.
