out the port on Reset, as, after
a power failure.)
NOTE: For all hardware flow control, CTS and DTR Switch 7
options must NOT be in the "forced active" position.
For no flow control and normal software flow controls
(X-ON/X-OFF and ENQ/ACK) the CTS and DTR
Switch 7 options should be in the "forced active" position.

NOTE: If your desired baud rate is within ±4% of one listed above, in most
cases you should set the CAP to the listed rate.
Make certain Switches S1 and S2 are set for the correct number of
data bits for the particular Data Code Set chosen (see Table 4-3 and
the code set list in Section 4.4).

*A CAP crossover cable must be attached to the CAP for it
to emulate DCE in addition to selecting the DIP switch
option to emulate DCE. See the Appendix for more on
cable pinning.
* *Buffer allocation is for data being received by that port,
(input data).
