How about to a serial LCD screen?
Still the same. use the SEROUT command to the serial LCD device
SEROUT, <pin>, <baud_rate>, (65, 66, 67)
if say you have received the three bytes.characters into variable b5, b6 and b7 respectively then
SEROUT, <pin>, <baud_rate>, (b5, b6, b7)
what you need to understand is that all computers and microcontrollers etc work in binary. All other representations such as decimal, hexadecimal or ASCII are for the benefit of human reading.
For example %01010101 = $55 = 85 dec = "U"
If you are using simple Tx and Rx modules connected directly to PICAXE chips then that will work but you need to add a preamble before you send the actual data and best to use a qualifier at the start of the data.
The best preamble is a series of say six $55 values, followed a pause whose duration is approx equal to the duration of sending one byte at the baud rate, then send the data.
