I understand that the 'newer' 56k parts do not support direct control via the SCI port as the older 56k parts did. I would like to control the 56371 via simple ascii commands from a RS232 port.
Are there any application notes describing a minimal control via a serial connection?
I'm considering using a 68xx (or a PIC) such that the (micro)USART would connect to the PC com port and the SPI port (of the micro) would connect to the 56371.
Any simpler ideas or suggestions?
