#### Miscellaneous Topics

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.
