[*1] You can not use Visual Studio 2005 Express Edition because the partial code of source code is MFC(C++).
[*2] Without written permission by the author (Takashi Teranishi), you may not distribute modified versions of this package, and may not distribute this package for profit.
[*3] Tera Term is distributed under Modified BSD License.
[*4] Icon designer is Tatsuhiko Sakamoto.
[*5] An SSH authentication agent for PuTTY and WinSCP.
[*6] Tera Term can not simultaneously display multi languages because it has not completely implemented as Unicode API. Now Tera Term mutually converts between Unicode(UCS-2) and MBCS. Also, Chinese version Windows can display Chinese characters when you configure the locale for Unicode.
[*7] If there is no communication for a long time in NAT network, SSH session may disconnect because the router will clear NAT table.
[*8] You can switch the message language by using the language file(lang\*.lng). You need to re-startup Tera Term to active new message language.
[*9] Using TTProxy.
