I want to verify that I am understanding this properly...
The serial communications on pins 0 an 1 are in TTL and not RS232 right?
Similarly with software serial, it's not proper RS232 right?
What I'd like to do is interface with a serial LCD (to save on the # of pins needed) and another RS232 device. As such I'd want to use the hardware serial for one and software serial for the other. How feasible is this? Do I need TTL to RS232 converters?
Thanks for any info including pointing me toward where I may RTFM.
