  • TX means transmit and RX receive, but it does get muddled beyond that. The RS-232 standard specifies them from the DTE side (such as computers) only, so they’re backwards for DCE (such as modems); and that’s the side you’re more likely to be building as a device. Between chips, Tx to Rx will almost always hold, but check the datasheets anyway.

No public wish lists :(
