4.2.2 Connecting to a DTE device
Standard straight-through cables are used when connecting to a serial DTE device (like a PC COM
port) that has a DB25 or DB9 male connector. If replacing a modem, avoid any modem handshake
issues by configuring the device's interface for “leased line” or “permanent modem” type connection.
