UNIX environments support virtually any terminal type, terminal definitions being held in a system database. This database must contain enough details for the terminal being used in order that Adis can function.
Adis uses the standard input and output device interfaces for terminal I/O and so such terminal I/O can be redirected but with the restriction that you must not redirect standard input from a file unless it is a terminal device.
So, for example, the following is legal:
cobrun prog < `tty` >`tty`
(use the appropriate (`) character) whereas redirecting the input from an ordinary file or /dev/null is not legal and could result in a run time error.
