reading standard output

[Mark Tamura]

how do you read data from standard output?  i'm writing a program that
sends data to a device and needs to read status back for error conditions.

i've tried using the flags field in the iob, however i still get the
bad file (errno = 9) message on the read(1, ... )

i'm on a decstation 3100 with ultrix v4.0

thanks, mt.
