MTTTY (Multi-Threaded TTY) is an easy to use Windows serial communications program.
Serial COM Port Terminal
Multi-Threaded TTY (MTTTY) is an easy to use serial terminal utility that you can use to communicate with the RS-232 serial ports on your device or development kit. It is multi-threaded in that you can run multiple instances of MTTTY for each serial port.
MTTTY is commonly used for:
- Displaying status messages sent from a device, such as when using iprintf().
- Reprogramming a new application image through the boot monitor.
- As a serial interface to any application.
How to set up the serial port
Port: The PC’s serial port you wish to use.
Baud Rate: The host computer and the attached serial device must agree on a speed or baud rate to use for the serial connection (the recommended setting for both is 115200).
Parity: Checks whether data has been lost or written over when transmitted between your host PC and your device (default = None).
Data Bits: The number of bits in a transmitted data package (default = 8).
Stop Bits: The stop bit follows the data and parity bits in serial communication. It indicates the end of transmission (default = 1).
Connect: Pressing the Connect button will acquire the PC serial port for the MTTTY application. No data can be sent or received unless the connection button has been selected.
How to enable software flow control
Software flow control is required for downloading an application image to any device without SDRAM, such as the Mod5213 Embedded Core Module or SBL2e Serial to Ethernet device.

Hey there, MTTTY is a great tool and I am using it a lot. Thanks for that! I open and close it a lot in debugging my Arduino applications. However every time I open it I have to adjust the font size. My question is: is there an easy way to put the default font size to 14 pnts?

Hi Ewoud,
We’re glad to hear that you like the MTTTY and have found it useful! Unfortunately, there isn’t currently an easy way to save the settings from session to session.
Kind Regards,

Hi.
how to automatically stop capture in mttty program?
Hi Xano,
You’ll need to disconnect it by hitting the Disconnect button. This should prevent it from capturing info on the selected COM port.

HI.
When the computer is restarted, the previous configurations of the program are lost.
how to make the app open automatically and restore its previous settings?
Thanks!
