altpin	This option should be enabled on a port when an RJ-45 8-pin cable is used and the Data Carrier Detect (DCD) signal is required. For example, altpin should be enabled on a port where an RJ-45 8-pin cable is used with a modem. See RJ-45 8-Pin Modem Cable and Setting TTY Options.
fastbaud	RealPort devices support baud rates in excess of the maximum baud rate supported by Linux. To enable the use of these fast baud rates, a ditty-rp parameter, fastbaud, has been provided. See the topic fastbaud Data Rate Mapping in the document Setting TTY Options.
Data Carrier Detect (DCD)	In some cases, depending on your operating system requirements and/or your device requirements, it may be necessary for the Data Carrier Detect (DCD) signal to be active on a port before it will function. See Data Carrier Detect.
