Immediate Character Input with "text_io.get"

     While recieving character input to a program, I am aware that the ope-
rating system can control whether the characters are input as soon as they
are entered from the keyboard, or whether they are buffered somewhere, and
only entered after the carriage return.

     In particular, I have written a C program that utilized this feature,
so that I executed a Unix command to enable immediate character input, ran
the C program, and was able to simulate the backspace key with some other
key, that the C program recognized (via C's "getchar") and didn't print.

     Does anybody know if the "text_io.get" procedure for character input
can also read in "immediate" input, so that processing can take place be-
fore the carriage return gets hit?  (If the information is necessary, I'm
using the Verdix compiler.)

     Also, does anybody know the Unix command to enable immediate input?
