Stand-alone RS-232C interfaces

Most external RS-232C interfaces come with a ROM containing RS-232C BIOS and additional MSX-BASIC instructions. The interfaces without the specific RS-232C BASIC ROM will not work with all serial applications. All interfaces with BIOS 1.0 or without BIOS are only I/O based.

Computers with optional RS-232C upgrade

All the concerned interfaces are only I/O based. With exception for the Mitsubishi ML-G30 Model 1, all the MSX computers with optional RS-232C upgrade have RS-232C BIOS 1.0, RS-232C BASIC and i8251 + i8253 as UART.
