I/O error in /dev/ttyp0

[Back young-joon]

 	Hi...
 
 	I suffered the I/O error message from /dev/ttyp0.
 	(/dev/ttyp0: I/O error )
 	So I couldn't telnet or rlogin to that host...
 	Only got 'Connection Closed.' message.
 
 	What shall I do?
 	and what should the system administrator do?
 	Any helpful comments will be appreciated..
 
 	Thanx in advance..
