problem sending/receiving data to 40x2 from PGM editor

[scamanderriver]

Hi
looking for help here to solve an issue I'm having ... (another big learning curve happening here)

I am trying to send data from the PGM editor (using the terminal via the serial programming cable) to a 40x2 using the SERRXD command.
using the below code it works fine within the Editor Simulation, BUT!!
when i send to the 40x2, problems occur
if i send 1 the LCD displays 49 which appears to be the lcd dec code for 1
if i send 12 the LCD displays also 49
it seems i can only send/receive the first digit(1) and that it is always received/displayed as the character dec value 49 (2 = 50 etc)
I don't understand what is happening, I need the 40X2 to receive and correctly display the full number 12.
I'm wondering if the issue here has something to do with "uncompressed BCD usually implies a full byte for each digit, whereas packed BCD typically encodes two decimal digits within a single byte"
I would be grateful if someone could please offer me an explanation to what is happening here. it'd be great to solve this.
Thanks

#PICAXE 40x2

'loops waiting for input from PC

if b10 <> 0 then : goto show :endif 'show the received i/p

SEROUT d.1,N2400,(254,128,"waiting  ",#b10)

pause 200

goto start

SHOW:'displays received number

pause 200

b10 = 0

You need # and to type 12(space) in the PE terminal

Excellent !! Thanks for that,
i had tried adding the # previously.
but having the (space) after 12 then sending bought success
why is this so? i don't need it with the editor simulation.
what does the (space) do?
cheers

The PICAXE chips needs to know the ASCII number has finished. Consider:

1space
12space
123space

Basically # keeps going forever until it gets any character that is not 0-9, it doesn't have to be space, this would work just as well

1?
12?
123?

The space terminates the number, lets the PICAXE know the number has ended. It's like the 'over and out' on a walkie-talkie as otherwise you never know if the sender is going to send some more or has finished.
