Try messing with ioctl settings on ttyS1
read man pages on ioctl and termio to see how to use it, but what you
need to do is to set non-canonical mode for that device. You also have
to mess with the timeout and min_chars fields of the ioctl structure to
get it working cleanly.
It has been a long time (8+ years) since I have had to write low level
UNIX serial control stuff in C, so I am quite rusty in that area.How
nice it is that such ancient knowledge is still relevant today ! Compare
that with using Win 2.1 API code on a 'modern' NT box ... urgh !
