I have an application that likes to take input from the keyboard one character
at a time without waiting for a carriage return.  This can be accomplished 
easily for a pad using the pad_$ calls and for and sio line using the sio_$
calls to place the input stream in raw mode.  I would also like to be able to
run the program over a TCP/IP connection using telnet but have not yet been
able to do so.

According to the Domain System Call Reference, the only way to access this
type of connection is to use the ios_$ calls, but I can find no documented
way to invoke raw mode using ios.  (ios_$inq_type_uid reports that the stream
type is pseudo-tty slave.)  I realize that I could probably accomplish this
in the UNIX environment using the appropriate ioctl, but unfortunately my
program was developed in the Aegis environment and I'm not quite ready
to change it to UNIX (at least not until SR10 hits the streets.)

Does anyone know how to place a stream in raw mode using ios?  If not, has 
anyone figured out a way to access pseudo-tty streams using something other
than ios?

Thanks in advance.
