+A terminal TCP client for BPQ32 packet radio nodes, written in C with an ncurses TUI. Connects via BPQTermTCP protocol, displays split output/monitor panes, supports real-time RF frame monitoring with port filtering, multiple simultaneous sessions, and built-in forms for ICS-213 and packet check-in.
 
 ## Features
 
 - ncurses TUI with split output and monitor panes
-- BPQ packet radio node support (BPQTermTCP protocol)
+- BPQTermTCP protocol (compatible with QtTermTCP)
+- Up to 4 simultaneous sessions with live background receive
 - RF monitor with per-port and frame-type filtering
 - Auto-populates port names from the BPQ server on connect
 - Scrollable output and monitor windows with history
 - Input history (Up/Down arrows)
 - Session logging to timestamped files
+- Function key bar (F1/F3–F10) at bottom of screen
+- ICS-213 General Message form with F2 background send
+- PKTNET Packet Check-In form
 - Multiple host configuration with quick connect
 - Unicode box-drawing borders on all menus
 
 ## Dependencies
 
 - GCC
-- ncurses (wide character support — `libncursesw6`)
