Ellenburg" Subject: Serial Port Speeds Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Sender: owner-freebsd-questions@freebsd.org Precedence: bulk X-Loop: FreeBSD.ORG Seasons Greetings, I am using a Compaq DeskPro 4000 Computer, with an add-on serial card with 16550A UARTs. The Compaq has embedded serial ports, but they are only have 16450 UARTs. These embedded serial ports have been disabled in the computer's bios. When FreeBSD boots (3.0-RELEASE), dmesg reports that sio0 and sio1 are both "16550A" ports. However, I can not appear to be able to set my port speeds greater than 57600. Doing so, and I can not talk to my modem (BitSurfr Pro). I've tried recompiling the kernel, and implicitly specifying "flags 0x20000" on each sio line in the kernel configuration file. Using that kernel, when FreeBSD boots, dmesg reports the UARTs as being "ST16550A" as opposed to just "16550A" using the GENERIC entries. There's already a device entry for /dev/cuaa0 (which ppp uses). Do I need to delete that dev entry, or sio* and remake them using MAKEDEV after I've rebuilt the kernel? Any pointers or suggestions would be greatly appreciated. Kinda hard to connect at 128kbps when your pipe only supports 57.6. ;-) Happy Holidays, George Ellenburg To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
