To set up the serial communications parameters, put a check in the Enable
checkbox, and make your parameter selections according to the information
provided in the table below.
Port Property Settings
The meanings of the property settings are given in the following table:
Setting Meaning
Baud Rate This sets the port’s data transfer speed. Choices are from 300—
115200 (drop down the list to see them all). Set this to match the
baud rate setting of the connected device. Default is 9600 (which
is a basic setting for many serial devices).
Data Bits This sets the number of bits used to transmit one character of
data. Choices are: 5, 6, 7 and 8. Set this to match the data bit
setting of the connected device. Default is 8 (which is the default
for the majority of serial devices).
Parity This bit checks the integrity of the transmitted data. Choices are:
None; Odd; Even. Set this to match the parity setting of the
connected device. Default is None (which is the default for the
majority of serial devices).
Stop Bits This indicates that a character has been transmitted. Set this to
match the stop bit setting of the connected device. Choices are: 1
and 2. Default is 1 (which is the default for the majority of serial
devices).
Flow Control This allows you to choose how the data flow will be controlled.
Choices are: None, Hardware (RTS/CTS), and XON/XOFF. Set
this to match the flow control setting of the connected device.
Default is None.
Enable Toggle
DTR
Enabling this parameter allows the DTR signal to toggle between
disabled and enabled when the port is occupied. Choices are: No
and Yes. Default is No.
Note: For some devices, in order for Enabled to work correctly,
you must first disable DTR (select No, then click Update), then
Enable it (select Yes, then click Update).
Online Detect This allows you to set the DSR signal to detect online status or not.
Choices are: None and DSR. Default is DSR.
Out CRLF
Translation
This allows you to select whether to send a Carriage Return and
Line Feed signal (CRLF), or only a Carriage Return signal (CR).
Choices are: None (which sends CRLF) and CRLF
→ CR (which
only sends CR), Default is None.
Note: If your device outputs double spaced lines, it means that a
line feed is automatically added to a carriage return signal. In that
case, choose CRLF
→ CR.
Suspend
Character
The Suspend character is used to bring up the Suspend Menu in
Telnet sessions (see Permissions, page 31).
Note: Valid characters are from A–Z, except H, I, J, and M. Those
four characters may not be used.
