I issued the command :
chdev -l 'tty0' -a parity='odd' and received the following :
Method error (/etc/methods/chgtty):
0514-062 Cannot perform the requested function because the specified device is busy
1) I have checked through 'ps -ef | grep tty0' and there was no such process. Is this the correct command to issue to find out whether the device is used?
2) How do I make the device not busy as I think my program causes the device to be busy? I've killed my program but the device is still busy!
3) Is there a command that I can use to test whether tty is working?
NB. My program was working perfectly on another machine's tty!!
