Ok. Thanks.Greg KH wrote:
Ok, but even wihtout 'cat'... I wrote my own application that basically does open( ), read( ) and close( ) on a serial device. Everything works ok until the close ( ). If something is still trying to send on the serial link, my computer freezes. (Works fine with a regular /dev/ttySx )Don't use 'cat' to talk to usb serial devices. Use a proper serial program like minicom. Otherwise you will get unknown results.
thanks,

Any idea ?
Yes, this problem is fixed in newer 2.4 kernels.
thanks,

And does that problem only affect pl2303-based devices, or other USB->serial as well ?
For instance, the doc that comes with my RedHat says Belkin F5U103 is suported. Is that true, or does it have the same bug ?
Thanks
