I just recently aquired an Edgeport/8s for use with Linux (currently running Fedora 14, kernel 2.6.34.7, but flexible). But I need to set the ports to RS422 and RS485. However, the ionmode utility provided does not work: [root@tommy utils]# ./ionmode -F /dev/ttyUSB0 ./ionmode GETMODE failed for port /dev/ttyUSB0 [root@tommy utils]# ./ionmode -F /dev/ttyUSB0 mode 0x01 ./ionmode SETMODE failed for port /dev/ttyUSB0 On closer inspection, the edge_ioctl() function in the io_ti.c module does not contain the hooks for neither ION_GETMODE nor ION_SETMODE. I was led to believe that it should already be included in recent 2.6 kernels, but anyway... Then I found (http://www.mail-archive.com/linux-usb- devel@xxxxxxxxxxxxxxxxxxxxx/msg28881.html) which apparently was not applied in full according to the follow-up. However, inspecting the patch versus the current mainline git source shows that most of the functionality of the patch is indeed implemented, except the aforementioned IOCTLs. As I'm not familiar with the history I was wondering if there is a rationale for not including the IOCTLs and what is needed to get the them in? -Frode -- ^ Frode Tennebø | email: frode@xxxxxxxxxxx | Frode@IRC ^ | with Standard.Disclaimer; use Standard.Disclaimer; | -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
