Strings......and how to join them

[skimask]

My TX line is :
SEROUT2 PORTc.2,16780,[ ((id<<6) + (rhtc/100<<3) + (temp/100))]

which seems not to be a problem

my RX line is
SERIN2 PORTc.4,16780,250,programstart,[str myvar\6]
but I don't get what I send. I'm sure there is a glaring error somewhere, but when I hserout myvar I get numbers, but not what I sent

You're only sending one byte, but expecting to receive 6? How does that work?

And your SEROUT doesn't make a lot of sense...
You're shifting id up 6 bits, adding in a number that may or may not fit into those next 3 bits, and doing the same thing with the last number. What's up with that?

Maybe it would be best if you showed your code rather than your broken snippets.
