Note:
A number of PC’s of an older generation use the Intel, National Semiconductor, or United
Microelectronics IC 8250 as the serial port UART. This is a comparatively inefficient circuit for current
purposes and does not necessarily support the M2BUS adapter at 9600 baud. The newer UART’s
NS16450 and NS16550AF of National Semiconductor offer solutions for these problems.
