The screen module lets you communicate with the connected teletype over ASCII-terminal and keyboard of the computer running piTelex. It can be accessed directly over the computer's display and keyboard connectors or via ssh (Windows: PuTTY). In most application cases, this module should be enabled.
This way the output of the teletype can be monitored and keystrokes can be sent to the printer as well as to piTelex. These keystrokes may consist of simple text, but may also contain commands to control the teletype or thr behaviour of piTelex.
If show_ctrl is set to True, screen will output system status messages which are described here
Setting show_info to True will output a lot of additional internal information from line state changes to print buffer fill grade. This is mostly useful for debugging purposes by the experts....

| test | print 6 lines of ".-=x=-.-=x=-. ...." |
| date | print DateTime String |
| font | enter font mode. In font mode, all entered characters are recoded so that they can be punched to tape in a human-readable baudot-art representation, see Font Mode |
| cli | enter cmdline interface, see CmdLine Interface |
| read | read, if necessary convert, and print the contents of <file>, see below
|
read <basename> allows for reading and inserting the contents of a file <basename>.<ext>, which must be located in or below a subdirectory ./read of piTelex and may have one of the following extensions. depending on the extension, piTelex performs different actions:
| Extension | Action |
|---|---|
| txt | ASCII Text in UTF-8 encoding, insert into stream |
| pix,pox | Convert file to binary format and write the contents to <basename>.bin
|
| bin,ls | Convert binary file to text on the fly and insert into stream |
<basename> will be converted to lower case before looking for the file, so "PiTelex" and "pITElex" will both refer to a file with basename "pitelex".
Note: Starting piTelex in foreground (from the shell) will lead you immediately to the screen interface, if enabled.
If piTelex is running in background, you can connect to it's screen output by means of
screenorbyobu. See Software installation for details
Note: Most of these commands are not directly provided by device
Screen, but because they will in most cases be used from the screen interface, they are described here for convenience.
