  2. A PCI Parallel Port Card: Moschip MCS9865 or WCH CH353 (Trex 2 communicates via LPT direct I/O).
  3. A Serial (COM) Port: Either onboard or USB-to-Serial (Prolific PL2303 or FTDI). No CH340 chips—they cause timing errors.
  4. Terminal Software: Putty, RealTerm, or the built-in Trex terminal.
