CRT causes HUNTER to treat the serial port as the display and keyboard rather than the internal LCD display and keyboard.
CRT sets keyboard and display functions to the RS-232 port.
The command is useful for entering programs quickly also characters not on HUNTER'S keyboard may be used.
Any standard VDU may be used. Baud rates and other parameters are set on HUNTER using 'Initialise Communications'.
Remember that a 'crossed' RS-232 lead is needed with GND, RXD and TXD circuits installed.
