veetee

veetee is a DEC VT terminal emulator for the Linux and Windows desktop. It aims at SmarTerm/Reflection-class compatibility with real DEC terminals — VT52 through VT525 — so that OpenVMS and other legacy DEC hosts, including DECforms, FMS, EDT, EVE/TPU and SMG$ applications, behave exactly as they do on the hardware.

It follows DEC's own documentation and factory Set-Up defaults. Behaviour borrowed from xterm is available only as an explicit option.

• Using veetee — the window, fonts, status line, Hold Screen, copy and paste
• Keyboard — how a PC keyboard maps to the DEC LK401, the keymap editor, key programming
• Terminal Models — what each model emulates and how it identifies itself
• OpenVMS — setting up DCL and applications for veetee, and recording them for testing
• Conformance Testing — unit tests, vttest, esctest2, session scripts and recordings

Status

Release 0.6.0 completes milestone M6 apart from the OpenVMS acceptance recordings, and starts M7:

• The VT100/VT102/VT52, VT220/VT320, VT420 and VT510/VT520/VT525 feature sets, including VT525 colour, the VT500 character sets, page memory and dual sessions.
• An LK401 keyboard map in a TOML file with a visual editor, VT500 modified-key sequences and VT520 key programming.
• Session recordings that replay through the emulator as tests.
• Original fonts drawn on DEC's own character cells: 10×16 and 6×16 dots on the VT420 and VT500 series, with Greek, Hebrew and Cyrillic.
• Telnet, SSH, serial and local connections on Linux and Windows.

The per-function status, with a source for each behaviour, is in the compatibility matrix. The project website is veetee.issinoho.com.
