TER This command puts the terminal in either terminal emulation mode or FormCaching application

transmit data to or receive data from a Host computer. In this mode, data input from bar code reader
or keyboard is displayed on screen and output to RS-232 port. Data received from the serial port is
displayed on the LCD screen. Communication parameters, such as baud rate, data bits, parity, stop
bits and flow control, must be set to be compatible with the destination in order to send data
properly.
COM This command puts the terminal in Kermit server mode. The following indicates the available Kermit
commands at the Host/PC side:

RAM disk
