Hello,
I've been trying to use a Bafo Technologies BF-810 USB to serial on my RedHat9 (2.4.20-8) box without success.
Here's a summary of what I've tried and some strange results I got
When I plug the device, usbserial and pl2303 are loaded ok. Then I connect a Win box with hyperterminal to the new port, and cat /dev/usb/ttyUSB0
First: The fist character is never received.
Don't use 'cat' to talk to usb serial devices. Use a proper serial program like minicom. Otherwise you will get unknown results.
thanks,
greg k-h
Any idea ?
Thanks
Mathieu
