TinyTERM provides several command-line parameters for controlling its startup behavior. They can be used in any combination that is not self-contradictory. The listed version is the first TinyTERM release that included the capability.

Though they are also command-line parameters, debug settings have their own page.

Parameter	Description	Version
-a1 telnet://address	Brings up OLE mode 1. This starts TinyTERM in the default browser with the URL helper address as shown and connects the session, using default.tpx for other connection settings.     tt -a1 telnet://192.168.1.12	4.02
-a2 file.tpx	Brings up OLE mode 2. This also starts TinyTERM in the default browser, using the listed tpx file for all settings.	4.02
-autowindowtitle	With no argument, this causes each TinyTERM window opened to be named "Session" with a corresponding letter: Session A, Session B, etc.     tt -autowindowtitle With an argument, the word "Session" is replaced by the specified string. Spaces are not allowed:     tt -autowindowtitle Finance produces windows titled Finance A, Finance B, etc. In either case, the first available letter will be used. For example, if you close the Session B window, the next window opened will use Session B as its title, regardless of other open windows.	4.8.1
-hostname	Launches TinyTERM and connects to the specified hostname or IP address. Uses the configuration info from the specified .tpx file, or from default.tpx if none is specified.     tt -hostname 192.168.1.12	4.8.3
-keyboard	Selects an alternate keyboard.dat file. Quotation marks are required if the path or filename includes a space.     tt -keyboard "C:\path\to\keyboard.dat"	4.8.6
-mkdefs	Does not run TinyTERM. Instead, it makes a new copy of default.tpx in the TinyTERM directory with all settings at default values. If the user does not have permissions to write to the install directory, this has no effect.	4.02
-nosplash	Starts TinyTERM without the introductory splash screen.	4.02
tpx1.tpx tpx2.tpx etc.	Opens the specified .tpx file(s). This is the only argument that does not start with a dash. Up to nine may be listed on a single command line, separated by spaces. The .tpx extension does not need to be supplied, as it will be assumed if it’s not present. Each file will open in a separate tab within a single TinyTERM window.	4.02
-writepath	Sets the directory for reading and writing custom user files. All .tpx files and .dat files will write to and be read from the specified directory. If a requested file is not found in that path, it will be drawn from the default copy in the TinyTERM install directory instead.     tt -writepath C:\Users\Public	4.65
