Options

<host>
Host name or IP address.
<host>:<TCP port#>
<host> with a TCP port number.
":" is placed between <host> and <TCP port#>.
<host> <TCP port#>
<host> with a TCP port number.
Space character(s) between <host> and <TCP port#>.
Number just after <host> is interpreted as a port number.
telnet://<host>[:<TCP port#>][/]
URL style - for telnet handler
TCP port number and "/" at the end are optional.
If TCP port number is omitted, use 23. (TCPPort setting in setup file is ignored.)
\\<server>\pipe\<pipe name>
Pipe name.
Connects to a named pipe <pipe name> on the <server>.
Connects to local named pipe by specifying \\.\pipe\<pipe name>.
/B
Telnet binary option.
/BAUD=<speed>
speed of serial port. Same as the /SPEED= option. Actually, the serial port driver may not reflect your speed.
/C=<serial port#>
Serial port By default, maximum serial port number is 256. It is configurable in MaxComPort setting.
/CDATABIT=<value>
Data bit of serial port
/CPARITY=<value>
Parity of serial port
/CSTOPBIT=<value>
Stop bit of serial port
/CFLOWCTRL=<value>
Flow control of serial port
/CDELAYPERCHAR=<value>
Transmission delay time per character of serial port(msec)
/CDELAYPERLINE=<value>
Transmission delay time per line of serial port(msec)
/DS
Disable displaying the "New connection" dialog on startup
/E
Disable TCPLocalEcho and TCPCRSend option
/ES
Enable displaying the "New connection" dialog on startup
When the port type is TCP/IP, "New connection" dialog is shown basically. However, the dialog can be not shown when HostDialogOnStartup is off. The /ES option can be forced to show the "New connection" dialog regardless of the setting.
When the port type is Serial, the "New connection" dialog does not be shown. Also, the /ES option can not be effected.
/F=<setup file>
Setup file
/F=TERATERM.INI (default)
If this value is not a full path, it is understood as a relative path from %APPDATA%\teraterm5\.
/FD=<file transfer directory>
File transfer directory
/H
Hide title bar.
/I
Iconify Tera Term window.
NOTICE: This mode can also be used with Windows task scheduler when a user is not logged in.
/K=<keyboard setup file>
Keyboard setup file
/K=KEYBOARD.CNF (default)
If this value is not a full path, it is understood as a relative path from %APPDATA%\teraterm5\.
/KR=<kanji code (receive)>
Note: Japanese, Korean and UTF-8 mode only
/KT=<kanji code (transmit)>
Note: Japanese and Korean mode only
/L=<log file>
Start Tera Term with logging.
File name can include formats of Tera Term and strftime.
If this value is not a full path, file name is converted to fullpath before open.
/LA=<language>
Language mode.
/M=<macro file>
Start Tera Term with macro.
If this value is not a full path, it is understood as a relative path from %APPDATA%\teraterm5\.
/MN=<multicastname>
Multicast name for sendmulticast macro command.
/NOLOG
Start Tera Term without logging.
/OSC52=<operations to permit>
operations to permit for clipboard access from remote host.
/P=<TCP port#>
TCP port number
/R=<replay file>
Replay file
/SPEED=<speed>
speed of serial port. Same as the /BAUD= option. Actually, the serial port driver may not reflect your speed.
/T=<telnet flag>
/TEKICON=<icon name>
TEK window icon.
Could be specified the same value of TEKIcon of setup file.
/THEME=<theme file>
Theme file
If this value is not a full path, it is understood as a relative path from %APPDATA%\teraterm5\.

Examples

TTERMPRO
TTERMPRO myhost.example.com
TTERMPRO myhost.example.com:23
TTERMPRO myhost.example.com 23
TTERMPRO 192.0.2.1
TTERMPRO myhost.example.com /T=0 /P=7
TTERMPRO \\.\pipe\vmware-serial-port
TTERMPRO /C=1
TTERMPRO /F=TELNET.INI
TTERMPRO foohost.example.org /F=FOOHOST.INI
TTERMPRO /C=2 /SPEED=9600 /F=MYSETUP.INI
TTERMPRO /K=MYKEY.CNF /W="My host"
TTERMPRO /R=README.TXT ; replay a file
TTERMPRO myhost /B /X=100 /Y=50
TTERMPRO /PIPE pipename ; same as \\.\pipe\pipename

Default values

Following default values are stored in the Tera Term setup file: 

<TCP port#>
/B
<speed>
<serial port#>
<file transfer directory>
/H
<kanji code (receive)>
<kanji code (transmit)>
<language>
<macro file>
<telnet flag>
<icon name>
<window title>
<window pos (x)>
<window pos (y)>

Note

[1] Only if <telnet flag> is 1 (on) and <TCP port#> is 23, Tera Term starts spontaneously sending telnet commands to the host for the option negotiation when the TCP/IP connection is established. In any cases, Tera Term can respond to telnet commands sent by the host.

[2] If the parameter value can include the space character and semicolon, a user should put the value in quotations by using `"' character.
If the value includes the `"' character, the user should write the `"' character two times.(version 4.63 or later) 

/F="C:\Document and Settings\user\My Documents\teraterm\server1.INI"
/W="Tera Term"
/W="""Tera Term"""
/W="Tera;Term"

[3] If portable.ini exists in the same folder of ttermpro.exe, ttermpro works as portable version
In portable version, the configuration file folder is the same folder of ttermpro.exe.
