USB to serial adaptors allow you to use RS232 based hardware via a computer's USB port.
I bought SiteCom's USB to serial cable and it works perfectly with Linux:
- open a console
- attach the adaptor
- read the syslog using the command
dmesg
- in the syslog you will find some lines reading like
[51904.256210] usb 2-1.6: new full speed USB device number 8 using ehci_hcd [51904.341896] usb 2-1.6: New USB device found, idVendor=067b, idProduct=2303 [51904.341904] usb 2-1.6: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [51904.341909] usb 2-1.6: Product: USB-Serial Controller D [51904.341912] usb 2-1.6: Manufacturer: Prolific Technology Inc. [51904.342508] hdj_probe() unsupported device, idVendor67b, idProduct:2303 [51904.342540] pl2303 2-1.6:1.0: pl2303 converter detected [51904.344545] usb 2-1.6: pl2303 converter now attached to ttyUSB0
Testing with another computer
To test with another computer I connect the USB to serial adapter to my USB port, the other end I connect via a female-female cable to an older computer's com2 port. Then I issue on my computer
dd if=/dev/urandom of=/dev/ttyUSB0
on the other computer I use
dd if=/dev/ttyS1
And I can see how garbage is transmitted.
I must show some appreciation to this wrietr for bailing me out of such a predicament. Right after surfing around through the the web and coming across views which are not powerful, I believed my life was over. Existing without the presence of strategies to the problems you have fixed as a result of your main blog post is a serious case, and the kind which could have badly affected my entire career if I had not come across your web blog. Your own personal capability and kindness in maneuvering every aspect was priceless. I don't know what I would have done if I had not discovered such a point like this. It's possible to at this time relish my future. Thanks for your time so much for the expert and amazing help. I won't hesitate to endorse the blog to anybody who should have care on this subject matter.
