RS-232

RS-232, now formally EIA-232, is the electrical definition for point-to-point serial data interfaces, and the Modbus serial line specification refers to it as the EIA/TIA-232 standard.

<!-- review notes

• sentence 1: support check: partial - The passages support EIA-232 (formerly RS-232) as the point-to-point serial electrical definition and RS232 as 'EIA/TIA-232 Standard', but they don't say the Modbus serial line specification is what refers to it that way. -->
