If you use a Wyse PC (M310 Workstation) you have a useful, and potentially dangerous, command available on your system: the LOCK command. LOCK allows the system user to secure the PC from unauthorized use even if the power has been disconnected and reconnected. To use the command, assign a four‐digit (numeric) combination to the system and execute LOCK at the DOS prompt. To unlock, execute UNLOCK with the four‐digit combination as a parameter. If you have Wyse PCs in areas where unauthorized use is likely (e.g., OPAC terminals) this facility can be quite useful.
