Save the session for late analysis by selecting “Session > Save session/Save session As” from the main menu. Click the “Start monitoring” button to begin the session.ħ. Your choices are device control, create/close or read/write.Ħ. Use the “Capture options” menu to select the events to be monitored. You can choose the “New window” option to start the session in a clean window.ĥ. Select “Start monitoring now” if you want to immediately start monitoring the ports. “Select all” or “Select none” can also be chosen as viewing options.Ĥ. Modbus view displays all transmitted Modbus data (RTU and ASCII).

Dump: two-way serial communication is shown in hexadecimal and string formats.

Table: recorded IRPs are displayed in the form of a table.

Terminal: presents the transmitted data as ASCII characters.

Line: displays lines of plain text containing IRP details.

Select the viewing mode which will be used to display the monitored serial data: The “New monitoring session” window should now be displayed. Alternate methods to start a new session are using the ‘Ctrl + N’ keyboard shortcut or clicking “New” on the toolbar.ģ. From the main menu select “Session > New session”. Launch the app and open a new monitoring session by following the next step.Ģ. To monitor your serial port activity, use these simple steps:ġ. The picture looks similar, only slightly faster.First case: monitoring the activity of serial ports You can use the parameters of Test-Connection to specify both the sending and receiving computers, to run the. You can use this cmdlet to determine whether a particular computer can be contacted across an IP network. ostream, 'eventformat', 'fcdc_serial' ) %% measure time t1 = toc tlop = %% disp received event disp ( ww ) pause ( 0.15 ) %% give serial port a break if count > 1000 break end end figure plot ( tlop * 1000, '.' ) xlabel ( 'function calls' ) ylabel ( 'delay read write event ' ) modal_val = mode ( tlop ( 2 : end ) * 1000 ) median_val = median ( tlop ( 2 : end ) * 1000 ) range_val = range ( tlop ( 2 : end ) * 1000 ) gtext () gtext ( num2str ( modal_val )) gtext ( num2str ( median_val )) gtext ( num2str ( range_val )) %% close what we have opened fclose ( 'all' ) delete ( instrfind ) The Test-Connection cmdlet sends Internet Control Message Protocol (ICMP) echo request packets, or pings, to one or more remote computers and returns the echo response replies. istream, event, 'eventformat', 'fcdc_serial' ) tic %% read ww = ft_read_event ( cfg. value = 5 %% This can be a string or an integer, e.g., 1 or 'Rock_n_Roll_will_never_dye', however longer strings will take longer to be communicated count = 0 tlop = while true count = count + 1 %% write ft_write_event ( cfg. ostream = 'serial:COM1?BaudRate=115200' event. istream = 'serial:COM4?BaudRate=115200' %% and receive it on serial port 1 (serila ports are physically connected) cfg. %% here key1 is BaudRate and value1 is 115200 %% write something to serial port 4 cfg.

We can send commands on one serial port and receive them on the other and then estimate the delay. Here we need a computer with two serial ports(or two computers). How to measure the delays of sending and receiving using a serial port connection If this doesn’t work just check the hardware connections.

Then once the connection is established you can type in the windows putty display and can then read it from the Linux putty display and vice versa.On the windows PC, open up a putty session and setup a serial port connection (click on serial), and specify the name of the port where the serial device is connected to (e.g., ‘COM3)’, make sure baud rate is the same as on the Linux machine(i.e.The main thing to consider is the baud rate (e.g., 115200), which has to be the same on sending and receiving end. Choose serial and type the path for the serial port (e.g., /dev/ttyS0/). On the Linux PC, open up a putty session by typing putty.To check that the serial connection between a Linux computer and a windows computer is functional, you can do the following: How can I test the serial port connection between two computers? A null modem cable is an RS-232 serial cable where the transmit and receive lines are crosslinked. Faq realtime What kind of cable do I need for a serial port connection between two computers?įor the type of connection we are talking about here, you need a so called ‘null modem cable’.
