I was wondering, is there a full duplex chip that doesn't require any shorts or connections or capacitors. I've worked with the MAX232 but I fee like it's an unnecessary pain to add capacitors. Even with the MAX233, you still have to short a couple of the leads...again, what's with the extra work? Is there a simple chip where all you connect is power, ground, UART I/O and RS232 I/O? Mind you, full duplex, I've also DS275, but even with that, you have to short one pair of leads and it's only half duplex.
