# MMCC mode

The normal mode is VT Terminal. All text from the device is sent to the terminal and keystrokes made in the terminal window are sent to the device.
Macros and command line text is also sent directly to the device. The command line box has a command scroll back buffer which make sending repetitive commands easy.
Many system messages are also sent to the terminal window.

External VT helper assumes the an external terminal program such as TeraTerm is connected to the data port. All data is transferred between the attached device and the terminal program. Additionally, you can send macros and other commands etc from the Control centre without interrupting the terminal session.
Terminal programs on the same PC should be set to localhost:50900 and Telnet or raw.

Note: If you are using TeraTerm you may have to make a change to it's ini file.
When using TCPIP, TeraTerm is usually configured to send data when it gets a line-end character.
This is to save sending lots of small packets but really stuffs up the user experience when typing. Changing it to character at a time will fix most problems.
Look for:
Line at a time mode
EnableLineMode=on
and change it to
EnableLineMode=off

Monitor / Hex monitor also assume a connected external terminal. MMCC will monitor and display text going between the terminal program and the attached device in ASCII or HEX.
This is very helpful when debugging VT control codes etc.

File manager opens a new window for viewing and transferring files between the PC and device.
See File Manager for more information.
