Description Andrew Cagney 2007-02-15 19:07:33 UTC 
The jline library creates a child process using Runtime.getRuntime().exec(cmd).
 This use of fork and SIGCHLD clashes with frys's control over the same components.
Comment 1 Andrew Cagney 2007-02-22 16:02:53 UTC 
The fix here is to create a PtyTerminal that extend jline.Terminal.  That code
then uses frysk.sys.termios to set/clear the terminal settings.

This needs to be common code, perhaphs in frysk-core/frysk.util, so that fhpd,
and the corresponding GUI instance of fhpd can share it.

There is an existing PtyTerminal in frysk.vtecli, that can be eliminated.
