Note With CS-series, a high-speed NT Link is available only with Serial Communi-
cations Boards or Serial Communications Units manufactured on or after
December 20th, 1999. With earlier models, only standard NT Link is available.
Except for the baud rate, the 1:N NT Link communications specifications are
fixed. Therefore, the port settings, start bits, stop bits, and parity need not be
