Free serial ports
One free serial port capable of 9600-bps operation is
required for a connection to each serial device
(ADU, modem, data module) or direct connection to
a Avaya Media Gateway.
We recommend that PCs have at least a 16550A
UART or 16550A UART simulator (capable of 56
kbps DTE-speed connections). USB and internal
modems should emulate this hardware.
A second serial port is required for simultaneous
connection to AUDIX through a serial connection.
