Re:UART comm w/ hardware flow control code?

Hi Derek,

Thanks for your multiple, valued contributions. Believe that one can never supply "too much" detail/explanation - I am still amazed at the fair/proper questions which remain after I thought I had clearly explained things.

Re: your sw Uart - may I suggest an I2C or SPI instead? (better yet - a selectable sw port) Most LMI devices have multiple hw Uarts! (some have three)

Few LMI have 2 I2C and 2 SPI - which is valuable for "chip to chip" communication - when each micro requires "unswitched access" to SPI/I2C accessories. Having to "switch/share" an SPI/I2C port slows traffic while adding a management layer and complications.

Believe this will be more welcome - keep up your valued work...
