The problem is that you can not use the port at any baud rate other than 9600 baud. The problem is two-fold. I have a fix for the first part. There is an incorrect definition of the static struct speedtab baud_table array. This should be an array of 2 element structures. As it is currently defined, it is a single structure will more than 2 elements. I tested this by breaking up the structure into multiple elements, and that works fine. I have isolated the second part, but have not yet come up with a resolution. The setting lock devices are not working properly (cualR0, ttylR0) with regards to the baud rate. If you set the lock device to zero baud, it will only let you access the device at zero baud. The same holds true for 1200, 2400, etc. The initial setting of this device starts at 9600 baud. I have not been able to locate a value that allows you to change the baud rate of the regular callout device (cuaR0) when you access it. I don't know if this problem is in rp.c or tty.c. I will keep trying to find it, but I would appreciate any assistance. Thanx, EBD >How-To-Repeat: Correct to the structure definition in rp.c. recompile and install new kernel. reboot stty -a < /dev/cualR0 baud rate will be 9600 baud. any value set on this device locks the baud rate. I have not found a value that permits the baud rate to vary. >Fix: Fix speedtab structure definition. ??? I don't know yet about the rest. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
