Hi,<BR>I&#039;ve been checking out home automation controllers and want to integrate them into the web so I can check temp, turn on/off lights etc etc. Since almost all of them have external hardware interfaces connected to RS232, I&#039;d like to know how I can access the serial port to send both ASCII and binary data?<BR><BR>By access I mean, open, write (and or read) and maybe close :-)<BR><BR>Since the hardware interfaces do all the tricky stuff I don&#039;t need to be concerned with latency, timing or other RTC stuff.<BR><BR>PS: Most of the "software" around, uses extremely gaudy GUIs with very idosyncratic features and reeks of amature!<BR><BR>Thanks in advance.
