Type Default Option
Boolean false

Defines the emulator's response to the TELNET DO TIMING MARK option. When set to false, the emulator will respond to DO TIMING MARK with WONT TIMING MARK, which is consistent with most modern TELNET clients.

When true, the emulator will respond with WILL TIMING MARK, which is consistent with the old BSD telnet command and with older versions of the x3270 family. In either case, the emulator will never respond to a DONT TIMING MARK option.
