✍
Your computer does not work with party lines, cannot be connected to a coin-operated
telephone, and may not work with multiple phone lines or a private branch exchange
(PBX). Some of these connections may result in excess electrical current and could
cause a malfunction in the internal modem.
If you connect a phone line coming through a splitter, the modem or connected device
may not work properly.
