The NS/VT protocol allows the host to set a time limit when it reads from the
terminal. If the read has not been satisfied within the set time limit, the
NS/VT client notifies the host and terminates the read. Typically, a host application
uses this capability for security and when notified that the read has timed
out, it automatically logs the user off of the host. A setting of Yes
means that timed reads are treated normally and the host is
notified when the time expires. A setting of No means that the time parameter of reads is ignored by the NS/VT client and that reads will never time out. The default setting is No.
