5. Use the Help button for additonal information.
6. Click Apply.
Note: Configure the serial port for the serial communication parameters (baud rate,
data bits, parity and stop bits) required by the connected IA device. If you
configure the port for a slave, you do not have to configure a network-based
master. Communication with the master just works. (If the master is
connected to a serial port, it must be configured, however.) If you configure a
port for a master and the slaves are located on the network, TCP sockets,
UDP sockets, and Modbus/TCP are all supported. Use the protocol required
by the master.
Chat Mode
This profile is only available for the PortServer TS 8 and PortServer TS 16.
This configuration allows multiple clients to simultaneously connect to or
manage a server connected to the same serial port -similar to a chat room.
In chat mode, the serial device can be a slave or a master. Enabling the
device as a server (slave) allows you to establish the end of line detection,
the timeouts, and the disconnect conduct. Server settings establish the
data echo direction. As a client (master) device, the same settings apply
but you may also direct your communication to a specific port or other
networked device.
Modem Profiles
There are 3 types of modem profiles:
• Modem Emulation
Modem Emulation allows the Digi device to function as a modem. A
short description follow the modem profiles listed below. For more
specific information about Modem Emulation see "Special Features:
Modem Emulation" on page 67, including AT commands specific to
this function.
• Modem
The Modem profile configures the Digi device for attaching a modem
to a serial port. For more specific information about the modem
