3.1.0.9 cgi

The `cgi` and `hcgi` terminal drivers support SCO CGI drivers. `hcgi` is for printers; the environment variable CGIPRNT must be set. `cgi` may be used for either a display or hardcopy; if the environment variable CGIDISP is set, then that display is used. Otherwise CGIPRNT is used.

These terminals have no options."
