I'm trying to get better speed from ubsa(4) to use a 3G modem att full speed. Editing ubsa.c up to 921600 is fine but if I go to 1228800 compile fails: cc -O2 -fno-strict-aliasing -pipe -D_KERNEL -DKLD_MODULE -std=c99 -nostdinc -DHAVE_KERNEL_OPTION_HEADERS -include /usr/obj/usr/src/sys/HUNTER/opt_global.h -I. -I@ -I@/contrib/altq -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -fno-common -g -I/usr/obj/usr/src/sys/HUNTER -mno-align-long-strings -mpreferred-stack-boundary=2 -mno-mmx -mno-3dnow -mno-sse -mno-sse2 -mno-sse3 -ffreestanding -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -c /usr/src/sys/modules/ubsa/../../dev/usb/ubsa.c /usr/src/sys/modules/ubsa/../../dev/usb/ubsa.c: In function 'ubsa_baudrate': /usr/src/sys/modules/ubsa/../../dev/usb/ubsa.c:534: error: 'B1228800' undeclared (first use in this function) /usr/src/sys/modules/ubsa/../../dev/usb/ubsa.c:534: error: (Each undeclared identifier is reported only once /usr/src/sys/modules/ubsa/../../dev/usb/ubsa.c:534: error: for each function it appears in.) *** Error code 1 Where can I dig out more info on how to proceed? Unfortunately my understanding of C and the rest is rather limited... Thanks!
