Chapter 5. Port Operating Modes
57
The Serial Console Server supports simultaneous connections from up to 16
host computers in this mode, allowing multiple computers to communicate
with the serial device at the same time.
Note: Be sure that the Socket entry specified on the Network page corresponds
to the port that the device listens on. 5301 is the Serial Console Server’s
default setting. (see
Network , page 95, and Base Socket , page 96).
TCP Client
In TCP Client mode, when serial data comes into the Serial Console Server’s
serial port, the Serial Console Server initiates contact with the host computer
and begins sending serial data to the to the host. The Serial Console Server can
send data to up to 16 host computers simultaneously, and supports 128-bit/256-
bit SSL (TLS v1.0 / TLS v1.1 / TLS v1.2) data encryption in this operating
mode.
UDP Mode
UDP (User Datagram Protocol) Mode is faster and more efficient at
communications than TCP. In UDP mode, communications are bilateral. A
serial device can send data to, and receive data from, up to 16 host computers
via the Serial Console Server’s COM port.
Because it doesn’t perform error checking in the thorough way that TCP does,
UDP is more suitable for real time applications (such as message display) than
the slower TCP which is optimized for data accuracy.
Virtual Modem
In Virtual Modem mode, the Serial Console Server’s COM port emulates a
modem. The port acts as if it were a real modem for communication with a
remote server. This allows software designed to transmit data over a serial
modem-to-modem link, to perform serial operations over a TCP/IP Ethernet
connection. In this mode, the Serial Console Server “dials into” the remote
server’s IP specifying the appropriate port address for the transmission. For
example:
atd 10.0.100.101:5000
A detailed description of the data structures and related functions of the Serial
Console Server’s virtual modem function is provided on page 148.
Note: 128-bit/256-bit SSL (TLS v1.0 / TLS v1.1 / TLS v1.2) data encryption
is supported in this operating mode.
