# Modifying TASWORD — RS-232 Printing

Step-by-step guide for modifying [TASWORD](http://localhost/tag/tasword/) to output to a serial printer (IBM PCjr thermal printer) via the TS-2068’s 2050 modem/RS232 interface. Involves disassembling TASWORD with ZEUS, modifying the 8251 UART initialization, reconfiguring I/O port addresses, and setting TASWORD interface control codes.
