If user settings are specified for the port settings, the number of start bits, data
length, number of stop bits, parity, and baud rate must be set. The start bits
setting, however, will be ignored and 1 start bit will always be used.
Do not set the baud rate setting to between B and F. A setup error will occur if
these settings are used, and the default setting of 9,600 bps will be used. Do
not use setting 1 and 2, which are reserved for the system.
If response frames cannot be completely received regardless of the communi-
cations processing used at the host computer, a send delay can be set for the
response. Any setting higher than 7530 Hex will be treated as 7530 Hex.

Send delay
If CTS control is enabled, the RTS signal is turned ON before starting to trans-
fer and then the send is started after confirming that the CTS signal is ON. If
CTS control is not enabled, the RTS signal is turned ON before starting to
transfer and then the send is started without checking the status of the CTS
signal.
