is the data transmission rate in bits per second, and the clock speed on a serial port
when the port is a physical DCE (i.e., the attached I/O cable is DCE). If this port is a
physical DTE, specify the line speed that matches (as closely as possible) that of the
device connected directly to the port.

If an RS-232 DCE port is directly connected to the DTE via the standard
Cabletron cable, the maximum supported speed is 64K. If longer cabling is
used, the maximum speed is 19.2K. (The EIA standard for RS-232
addresses speeds up to 19.2 Kbps.)
