v0.3.2

Says what else the server is for: any device on a serial port, not only
telecommunication equipment.

Changed

• Descriptions now also say what else the server is for: any device on a serial
  port, in raw, ANSI or VT100 mode, such as IoT gateways, alarm and control
  panels, UPS and PDU menus, lab instruments and industrial controllers. README
  opening, PyPI summary and keywords, registry title, serial-console skill,
  connect tool description, and the Field Guide cover, chapter A, chapter C,
  a new "everything else" row in the device playbook, and the terminal modes
  table.

v0.3.1

Leads with what the server is for: AI configuring telecommunication equipment
through its console port. Adds the Junos and IOS operating skills, verified on a
Juniper EX2200, and fixes prompt matching after Junos redraws a line.

Changed

• Registry title and description, PyPI summary, keywords and classifiers,
  README opening and Field Guide cover now lead with AI for the configuration of
  telecommunication equipment: Juniper and Cisco routers and switches, Icom CI-V
  and Kenwood, Yaesu and Elecraft CAT transceivers, GS-232 antenna rotators.

Added

• Operating skills junos-operating and ios-operating (skills/): modes
  from the prompt, shell/CLI/configure transitions, commit and rollback or the
  IOS reload-timer discipline, everyday show commands, recovery. Field Guide
  chapter 06.
• Both skills checked against the real CLI. Junos shell transitions (cli,
  exit, start shell, cli -c) and every listed show command were run on
  the EX2200. Neither Junos nor IOS has show system status, and IOS has no
  show interfaces brief or | last; the skills now say what to use instead.
  The IOS skill had show logging | last 50, which is Junos syntax; fixed.
• Junos pager, ? help and configuration mode (configure exclusive,
  commit check, edit/up/top, run show, rollback 0, exit) run on
  the EX2200 with nothing committed. The pager line is ---(more)--- or
  ---(more NN%)---; the skill now matches the prefix and says to press q
  before typing, because keys at the pager are pager commands.

Fixed

• Prompt matching in ansi, vt100 and xterm mode sees the last line as the
  terminal shows it, up to the cursor. Junos redraws an edited line with a CR,
  padding spaces and backspaces after ? and Ctrl-U, so the
  bytes ended in \b and read_until_prompt and expect timed out on any
  prompt ending in $, the juniper-craft default [#>%] ?$ included (seen
  on the EX2200-C). A line that has ended, or that a bare CR has just rewound,
  is never taken for a prompt; dumb mode still matches the bytes exactly.
  Field Guide chapter 05; the junos-operating skill no longer needs a bare
  return after ? or Ctrl-U.

Verified

• Live session on 2026-09-15: the 0.3.0 PyPI package, launched via uvx as
  Claude Desktop does, drove a Juniper EX2200-C (Junos 15.1R6.7) console over
  a Prolific PL2303 adapter: juniper-craft preset, one expect sequence from
  shell to CLI through three show commands and back, annotated capture. The
  first hardware run; everything before it was the simulated port.
• _hosttest/juniper_login_check.py: interactive login check that asks for
  credentials with getpass.

v0.3.0

The terminal release: the VT100 / ANSI / xterm family, as an agent needs it.

Added

• Terminal modes on connect(terminal=...) and in presets. dumb (default)
  passes raw bytes. ansi strips colour and escape sequences as bytes arrive
  (chunk-safe) and renders CR overwrites, backspaces, erase-line and cursor
  moves, so shells, coloured prompts and progress bars read cleanly and prompt
  matching works through the colour codes. The console presets use it.
• Screen model (terminal="xterm" or "vt100", cols/rows): a real
  character grid kept by pyte, for BIOS setup, RAID/BMC consoles, menu-driven
  switches, vi/top. The screen tool shows it with the cursor position; the
  terminal answers device-attribute and cursor-position queries as a VT100.
  Installed with the [screen] extra; the installers include it. Without it,
  xterm falls back to ansi with a note.
• send_keys: Ctrl-C and the other control keys, Esc, Tab, Enter, arrows,
  Home/End, Page Up/Down, Insert/Delete, F1..F12, single characters and
  text: runs, encoded as an xterm sends them. Interrupt a ping, complete a
  command, walk a menu. Read-only mode allows named keys, refuses literal text.
• Presets xiegu-civ (G90/X6100 speak CI-V, address 0x70; note on Baofeng and
  other handhelds having no CAT) and screen-console (115200 8N1, xterm 80x25).
• Transcript and reads render through the connection's terminal mode.

Changed

• 30 tools (was 28), 12 presets (was 10), 73 tests.

v0.2.0

The "shack" release: several ports at once, control lines, presets, expect
sequences, capture, and diagnostics. Existing single-port conversations keep
working unchanged; every new argument has a default.

Added

• Several ports at once. connect(name="rig"), connect(name="rotator");
  every tool takes connection= and defaults to the most recently used one.
  status lists all; disconnect(all_connections=True).
• Device presets. connect(preset="kenwood-cat") and friends load the
  family's usual baud, framing, flow control, line ending and prompt; explicit
  arguments override. list_presets shows them: cisco-console, juniper-craft,
  linux-console, kenwood-cat, elecraft-cat, yaesu-cat, icom-civ, yaesu-rotator,
  arduino, nmea-gps.
• Per-connection defaults. connect(line_ending=..., prompt=...) sets what
  send_text, query_text and read_until_prompt use when not told otherwise.
  Say "this device wants LF" once.
• Control lines. set_lines(dtr, rts), pulse_line("DTR", ms),
  send_break(ms); status reports CTS/DSR/CD/RI/DTR/RTS. Key a rig's PTT,
  reset an Arduino, interrupt a boot.
• expect. A list of send-and-wait steps in one call, for login flows and
  scripted command sequences, with auto_reply for pagers (--More--).
  read_until_prompt accepts auto_reply too.
• Capture. capture_start(path, format="raw"|"annotated") /
  capture_stop. Raw is a terminal log; annotated is timestamped TX/RX lines.
• Transcript. get_transcript returns the rolling last 256 KB received on
  a connection regardless of what reads consumed; also the MCP resource
  serial://transcript/{name}.
• Diagnostics. port_in_use_by(port) names the process holding a port
  (lsof); the busy-port hint on connect includes it. detect_baud(port)
  tries common rates and ranks them by how readable the reply is.
• Text CAT helpers. cat_build and cat_parse for the Kenwood, Elecraft
  and Yaesu ; protocols: frequency sets, rig ID to model, FA/FB, MD, IF
  decoding, and the ?; E; O; error replies.
• Icom CI-V helpers. civ_build, civ_parse (frames, echo vs. reply,
  BCD frequency, mode, OK/NG, PTT) and civ_freq.
• Rotator helpers. rotator_build and rotator_parse for GS-232A/B:
  read, move, move with elevation, stop, jog, speed; +0180, +0180+0045
  and AZ=180 EL=045 replies.
• Read-only mode. SERIAL_CONSOLE_READ_ONLY=1 refuses writes except
  read-style commands (show/display/get, two-letter CAT reads, CI-V read
  frames) and refuses control-line changes; SERIAL_CONSOLE_ALLOW overrides
  the allowlist.
• Idle auto-close. SERIAL_CONSOLE_IDLE_MINUTES=15 closes ports left
  idle, so a forgotten connection stops blocking WSJT-X. Off by default.
• The serial-console operating skill (skills/serial-console/SKILL.md).
• list_serial_ports marks ports already open here.

Changed

• read_until_prompt with no prompt anywhere now falls back to "the received
  text ends in #, >, $ or %" instead of a bare literal #.
• reconnect_last(name) reopens a named remembered connection; the remembered
  file now holds every connection by name (0.1.x files are read transparently).
• The unused timeout argument of connect is gone.
• 28 tools (was 11); 54 tests.

v0.1.1

Added

• server.json and the README mcp-name marker so the package can be listed
  in the official MCP Registry as io.github.sbrunner-atx/serial-console-mcp.

Changed

• Release workflow publishes with a repository token secret and can be run by
  hand; Trusted Publishing wiring kept.
• Installer builds install the [freeze] extra (mcp[cli] is needed by
  --collect-all mcp); Inno [UninstallRun] no longer uses a flag it rejects.

v0.1.0

First public, experimental release.

Added

• Eleven tools: list_serial_ports, connect, reconnect_last, send_text,
  send_hex, read_until_prompt, read_available, query_text, clear_buffer,
  status, disconnect.
• Interactive-console model: a background reader drains the port into a buffer
  from the moment it opens; reads match a literal or regex prompt and push
  leftover bytes back, or return once the line goes idle.
• Every Quick-Connect setting on connect: baud, data bits, parity, stop bits,
  RTS/CTS and XON/XOFF. Default 9600 8N1, no flow control. Settings are
  remembered for reconnect_last.
• Console script serial-console-mcp; serial-console-mcp configure writes the
  Claude Desktop config entry (merging, with backup) and --remove undoes it.
• Windows (Inno Setup) and macOS (.pkg) installers built by CI on v* tags.
• The serial-console-mcp Field Guide (docs/).
• 37-case test suite on a simulated serial port; CI on Linux, macOS, Windows.

Notes

• The MCP SDK is pinned <2; the 2.x line removed mcp.server.fastmcp.
• A dead reader (unplugged adapter) is reported by every tool instead of a
  silent timeout; the receive buffer is capped at 4 MB.
• Verified with the simulated port and a live MCP stdio handshake. A run against
