Okay the differences seem to be:

You have the following settings that I don't have:
bs0
cr0
ff0
nl0
tab0
vt0

I have the following settings that you don't have:
-flusho
-loblk
-parext
-pendin
tab3

You have these set that I have unset:
clocal
hupcl
ignbrk

You have these unset that I have set:
echoctl
echoe
echok
echoke
imaxbel
onlcr (It looks like this may be it.)

Again, I'll come back to what this means.

Thanks for pointing out stty to me. I don't know why it didn't occur to me before.
