The setting for the port settings determines if the default settings or user set-
tings will be used for port 1 and port 2. Be sure to use the same settings as
the RS-232C port on the host computer connected via the Host Link System.
If the default port settings are specified, then the settings of bits 00 to 04 and
the baud rate in D32001 will be ignored.
The default settings used are as follows: Baud rate: 9,600 bps, start bits:
1 bit, data length: 7 bits, parity: even, and stop bits: 2 bits.
m = D30000 + 100 × unit number
