I'm building linux kernel 2.1.106 on my linux box. I'm having the following question: Originally I was using linux kernel 2.1.99 and it can't automatically recognize my serial port /dev/ttyS1(it's a gateway fax/modem), so I issued the following command /bin/setserial /dev/ttyS1 irq 3 spd_vhi autoconfig in my rc.serial file and it worked. With the new serial.c in 2.1.106, somehow it refuses the above command and reports I/O error (looks like it's thinking there is no such serial port existing on my machine). I believe it's not a bug but is the result of the update on new serial.c (related to some kind of flags). Right now I'm using the kernel 2.1.106 but copy the old serial.c (2.1.99) into 2.1.106 source tree. I don't like such solution since I often update my kernel. Anyone has any idea? (Guess I have to wait until a new kernel can recognize my ttyS1 or the future serial.c can provide some kind of back compatibility on this) Thanks xun -- PLEASE read the Red Hat FAQ, Tips, Errata and the MAILING LIST ARCHIVES! http://www.redhat.com/RedHat-FAQ /RedHat-Errata /RedHat-Tips /mailing-lists To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject.
