I finally did this and here is what it says:
329 rbuxid CALL open(0x8001ba0,0x2,0x1b6)
329 rbuxid NAMI "/compat/linux/dev/finsim"
329 rbuxid NAMI "/dev/finsim"

329 rbuxid RET obs_vread 0
329 rbuxid CALL ioctl(0x3,0x5405 ,0x8003bc0)
329 rbuxid RET ioctl 0
329 rbuxid CALL ioctl(0x3,0x5407 ,0x8003bd8)
329 rbuxid RET ioctl 0
329 rbuxid CALL old.sigvec(0x3,0xefbfdb54)
329 rbuxid RET old.sigvec 0
329 rbuxid CALL dup2(0xefbfdb10)
329 rbuxid RET dup2 671899648/0x280c6000
329 rbuxid CALL ioctl(0x3,0x5401 ,0xefbfdb18)
329 rbuxid RET ioctl 0
329 rbuxid CALL old.lseek(0x3,0,0)
329 rbuxid RET old.lseek 0

329 rbuxid GIO fd 3 wrote 80 bytes

329 rbuxid RET write 80/0x50
329 rbuxid CALL old.lseek(0x3,0,0)
329 rbuxid RET old.lseek 0
329 rbuxid CALL obs_vread(0xe,0xefbfdc34,0xefbfdc24)
329 rbuxid RET obs_vread 0
329 rbuxid CALL recvmsg(0xa)
329 rbuxid RET recvmsg 10/0xa
329 rbuxid CALL read(0x3,0x280c6000,0x10000)
329 rbuxid PSIG SIGALRM caught handler=0x8000c40 mask=0x0 code=0x0
329 rbuxid RET read -1 errno -4 Unknown error: -4
329 rbuxid CALL ioctl(0x3,0x5407 ,0x8003bd8)
329 rbuxid RET ioctl 0
The call to read() apparently fails, but errno -4 is undefined, as far as I
know. Unfortunately, I do not have source to the program.
I'm running as root, so permissions shouldn't be an issue. I can tip to
the port, and if a modem is attached, talk to it just fine.
If anyone can offer clues as to what's going in in the above trace, I would
be very grateful!
