## 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>

  Connects to a named pipe <pipe name> on the <server>.
  Connects to local named pipe by specifying \\.\pipe\<pipe name>.

  - /C=2 COM2
  - /C=3 COM3
  - :
  - /C=256 COM256
  By default, maximum serial port number is 256. It is configurable in MaxComPort setting.

/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.

## 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"
