Dear all:
I have some questions about cygwin:
1. how can I access my xp serial port, even on of them is USBtoSerial
    I have google this question. I can see there is /dev under my
cygwin. But I have no /dev/ttyS[0-9] under my /dev.
Does that mean what I have to do is create the device node ttyS[0-9].
I mknod it but it tells me the file exist already like below

$ pwd
/dev
cd AT PC9 /dev
$ ls -lht
total 4.0K
lrwxrwxrwx 1 ???????? Users 13 Mar 25 15:40 fd -> /proc/self/fd
lrwxrwxrwx 1 ???????? Users 15 Mar 25 15:40 stderr -> /proc/self/fd/2
lrwxrwxrwx 1 ???????? Users 15 Mar 25 15:40 stdout -> /proc/self/fd/1
lrwxrwxrwx 1 ???????? Users 15 Mar 25 15:40 stdin -> /proc/self/fd/0
cd AT PC9 /dev
$ mknod ttyS0 c 4 64
mknod: `ttyS0': File exists
cd AT PC9 /dev
$

2. is there mips toolchain running on cygwin I can download instead of
downloading buildroot to build it?
appreciate your help,
miloody
