DTE versus DCE Most devices, except modems, are Data Terminal Equipment (DTE) devices. Modems are Data Communication Equipment (DCE) devices. Comtrol ports are configured as DTE. How you build a cable depends on which device your are connecting to (DTE or DCE).
If the Comtrol device falls within the limits for a Class A computing device established by the FCC, the serial cables used to connect the Comtrol device to the external devices must be shielded. The cable shield must connected to the chassis ground at both ends to reduce EMI.
