# tvi{912,920}[bc] - TeleVideo TVI-912B/TVI-920B and TVI-912C/TVI-920C

#
# Someone has put a scanned copy of the manual online at:
#     http://vt100.net/televideo/912b-om/
#
# These terminals were produced ca. 1979, and had a 12" monochrome
# screen, supported 75-9600 baud (no handshaking), monochrome, 7-bit
# ASCII, and were generally similar to adm3a but with attributes
# (including some with magic cookies), fancy half-duplex mode, and
# different bugs.
#
# Some operations reqire truly incredible amounts of padding. The
# insert_line (<il1>) and delete_line (<dl1>) operations in particular
# are so slow as to be nearly unusable.
#
# There may or may not have been a separate, earlier series of 912/920
# terminals (without the "B" and "C" suffix); I have never seen one,
# and the manual only describes the "B" and "C" series. The 912 and 920
# are quite distinct from the 914 and 924, which were much nicer non-
# magic-cookie terminals similar to the 950.
#
# This is a new description for the following TeleVideo terminals,
# distinguished chiefly by their keyboards:
#
#   TVI-912B - very odd layout, no function keys (84 keys)
#   TVI-920B - typewriter layout, no function keys (103 keys)
#   TVI-912C - very odd layout, function keys F1-F11 (82 keys)
#   TVI-920C - typewriter layout, function keys F1-F11 (101 keys)
#
# To choose a setting for the TERM variable, start with the model:
#
#    Model  || base name
# ----------||-----------
#  TVI-912B || tvi912b
#  TVI-912C || tvi912c
#  TVI-920B || tvi920b
#  TVI-920C || tvi920c
#
# Then add a suffix from the following table describing installed options
# and how you'd like to use the terminal:
#
#   Use Video | Second | Visual |  Magic  |  Page || feature
#  Attributes |  Page  |  Bell  | Cookies | Print || suffix
# ------------|--------|--------|---------|-------||---------
#      No     |   No   |  N/A   |   N/A   |   No  || -unk
#      No     |   No   |  N/A   |   N/A   |  Yes  || -p
#      No     |  Yes   |   No   |   N/A   |   No  || -2p-unk
#      No     |  Yes   |   No   |   N/A   |  Yes  || -2p-p
#      No     |  Yes   |  Yes   |   N/A   |   No  || -vb-unk
#      No     |  Yes   |  Yes   |   N/A   |  Yes  || -vb-p
#     Yes     |   No   |  N/A   |    No   |  N/A  ||
#     Yes     |   No   |  N/A   |   Yes   |  N/A  || -mc
#     Yes     |  Yes   |   No   |    No   |  N/A  || -2p
#     Yes     |  Yes   |   No   |   Yes   |  N/A  || -2p-mc
#     Yes     |  Yes   |  Yes   |    No   |  N/A  || -vb
#     Yes     |  Yes   |  Yes   |   Yes   |  N/A  || -vb-mc
#
# So e.g. a model 920 C with second page memory option, visual bell
# and no magic cookies would be tvi920c-vb; a model 912 B without the
# second page memory option and using magic cookies would be
# tvi912b-mc
#
# PADDING
#
# At 9600 baud, the terminal is prone to overflow its input buffer
# during complex operations (insert/delete
# character/line/screen/page), and it does not signal this over the
# RS232 cable. The typical symptom of an overrun is that the terminal
# starts beeping, and output becomes garbled.
#
# The padding delays in this terminfo were derived using tack(1)
# running on a Linux box connected to a TVI-920C with a later-model
# (A49C1-style) ROM running at 9600 baud, so your mileage may
# vary. The numbers below seem to give the terminal enough time so
# that it doesn't overflow its input buffer and start losing
# characters.
#
# KEYS
#
# If you want to use the FUNCT key on a tvi912[bc], use the
# corresponding tvi920[bc] terminfo with FUNCT + ... equivalents from
# the following table (these also work on the 920 series):
#
# Unshifted Function Keys:
#
#  Key | capname|| Equivalent
# -----|--------||------------
#   F1 |  <kf1> || FUNCT + @
#   F2 |  <kf2> || FUNCT + A
#   F3 |  <kf3> || FUNCT + B
#   F4 |  <kf4> || FUNCT + C
#   F5 |  <kf5> || FUNCT + D
#   F6 |  <kf6> || FUNCT + E
#   F7 |  <kf7> || FUNCT + F
#   F8 |  <kf8> || FUNCT + G
#   F9 |  <kf9> || FUNCT + H
#  F10 | <kf10> || FUNCT + I
#  F11 | <kf11> || FUNCT + J
#
# Shifted Function Keys:
#
#  SHIFT + Key | capname|| Equivalent
# -------------|--------||------------
#   SHIFT + F1 | <kf12> || FUNCT + `
#   SHIFT + F2 | <kf13> || FUNCT + a
#   SHIFT + F3 | <kf14> || FUNCT + b
#   SHIFT + F4 | <kf15> || FUNCT + c
#   SHIFT + F5 | <kf16> || FUNCT + d
#   SHIFT + F6 | <kf17> || FUNCT + e

# 3 Closed, 4 Open:	DTR is connected to RTS
# 3 Closed, 4 Closed:	Not allowed
#
# 5 Closed:	HDX printer (hardware control) Rev. K with extension port off,
# 		all data transmitted out of the modem port (P3) will also be
# 		transmitted out of the printer port (P4).
#
# 6 Open, 7 Open:		Not allowed
# 6 Open, 7 Closed:	20ma current loop input
# 6 Closed, 7 Open:	RS232 input
# 6 Closed, 7 Closed:	Not allowed
#
# Jumper options:

# is switched on).
#
# S4/W31:	Enables automatic LF upon receipt of CR from
# 		remote or keyboard.
# S4/W32:	Enables transmission of EOT at the end of Send.  If not 
# 		installed, a carriage return is sent.
# S4/W33:	Disables automatic carriage return in column 80.
# S4/W34:	Selects Page Print Mode as initial condition.  If not 
# 		installed, Extension Mode is selected.
#
# NON-STANDARD CAPABILITIES
#
# Sending <u9> or <u7> returns a cursor position report in the format
# YX\r, where Y and X are as in <cup>. This format is described in
# <u8> and <u6>, but it's not clear how one should write an
# appropriate scanf string, since we need to subtract %' ' from the
# character after reading it. The <u9> capability is used by tack(1)
# to synchronize during padding tests, and seems to work for that
# purpose.
#
# This description also includes the obsolete termcap capabilities
# has_hardware_tabs (<OTpt>) and backspaces_with_bs (<OTbs>).
#
# FEATURES NOT YET DESCRIBED IN THIS TERMINFO
#
# The FUNCT modifier actually works with every normal key by sending
# ^AX\r, where X is the sequence normally sent by that key. This is a
# sort of meta key not currently describable in terminfo.
#
# There are quite a few other keys (especially on the 920 models,) but
# they are for the most part only useful in block mode.
#
# These terminals have lots of forms manipulation features, mainly
# useful in block mode, including "clear X to nulls" (vs. "clear X to
# spaces"; nulls are sentinels for "send X" operations); "send X"
# operations for uploading all or part of the screen; and block-mode
# editing keys (they don't send escape sequences, but manipulate video
# memory directly). Block mode is used for local editing, and protect
# mode (in conjunction with the "write protect" attribute,
# a.k.a. half-intensity outside of protect mode) is used to control
# which parts of the screen are edited/sent/printed (by <mc0>).
#
# There are at least two major families of ROM, "early" and
# A49B1/A49C1; the major difference seems to be that the latter ROMs
# support a few extra escape sequences for manipulating the off-screen
# memory page, and for sending whole pages back to the host (mainly
# useful in block mode.) The descriptions in this file don't use any
# of those sequences: set cursor position including page (\E-PYX,
# where P is \s for page 0 and ! for page 1 [actually only the LSB of
# P is taken into account, so e.g. 0 and 1 work too,] and Y and X are
# as in <cup>); read cursor position (\E/), which is analogous to <u9>
# and returns PYX\r, where P is \s for page 0 or ! for page 1, and YX
# are as in <cup>, and some "send page" features mainly useful for
# forms manipulation.
#
# The keyboard enable (\E") and disable (\E#) sequences are unused,
# except that a terminal reset (<is2>) enables the keyboard.
#
# Auto-flip mode (\Ev) is likely faster than the scrolling mode (\Ew)
# enabled in <is2>, but auto-flip is very jarring so we don't use it.
#
# BUGS
#
# At least up to the A49B1 and A49C1 ROMs, there are no \Eb and \Ed
# sequences (I infer that in some TeleVideo terminal they may invert
# and uninvert the display) so the <flash> sequence given here is a
# cheesy page-flip instead.
#
# The back_tab (<cbt>) sequence (\EI) doesn't work according to
# tack(1), so it is not included in the descriptions below.
#
# It's not clear whether auto_left_margin (<bw>) flag should be set
# for these terminals; tack says yes, so it is set here, but this
# differs from other descriptions I've seen.
#
# Extension print mode (<mc5>) echoes all characters to the printer
# port [in addition to displaying them] except for the page print mode
# sequence (<mc4>); this is a slight violation of the terminfo
# definition for <mc5> but I don't expect it to cause problems.  We
# reset to page print mode in <rs1> since it may have been enabled
# accidentally.
#
# The descriptions with plus signs (+) are building blocks.
