M260 A5 B65 ; Send 'A' to address 5M260 A0x7F B0x41 ; Send 'A' to address 7F (hex)M260 A0 B82:101:112:82:97:112 ; Send 'RepRap' to address 0
Would two M260 commands be the solution?
Or, do those colons demarcate the byte values?
Did you try that? If not, why not?
but I'd like to present options for integrating the peripheral.
