For serial ports (COM1, COM2 and COM3), data rates higher than 115200 bit/s are not supported by standard PC hardware. Special computer hardware may be required for higher rates, including 230400 bit/s and 460800 bit/s. |
|
|
Upon power-up, COM3 is enabled by default. COM3 is multiplexed with EVENT2. To enable EVENT2, issue the following commands: INTERFACEMODE COM3 NONE NONE EVENTINCONTROL MARK2 ENABLE When EVENT2 is enabled, COM3 is disabled. |
