COM1 is the primary RS-232 serial communication port for the controller. Normally, this channel is configured to be a command interface that accepts Console requests and replies in human-readable text. In this mode, this port can be connected to an ASCII terminal emulation program such as HyperTerminal for direct operator interaction or may be connected to a host computer that issues commands and listens to replies. Alternatively, this serial port can be configured as a communications interface controlled by a GPL procedure; in this mode, it is referenced as device /dev/com1.
NOTE: Like COM2, the secondary serial interface, this primary serial interface does not support hardware flow control.
