A newbie question (I hate that word...)

Archiver

I am TRYING to send serial data (simply) from the BS1 to the BS2, the trouble is
that it's not working. Please tell me if this is correct syntax for sending and
recieving and if this will work:
Sending the decimal number 45 from bs1 to bs2 at 300baud. BS1 waits one sec,
then sends....bs2 waits 5 sec for data. THIS DOESN"T WORK. What the heck am I
doing wrong? Any help is always appreciated...

'{$STAMP BS1}
PAUSE 1000
SEROUT 0, T300, ( #45 )
HIGH 7
END

'{$STAMP BS2}
databyte VAR BYTE
SERIN 0, 3313, 5000, nodata, [noparse][[/noparse]DEC databyte]
DEBUG DEC databyte
END

nodata:
HIGH 7
END

Hi Astro,

The BS2 is left waiting for more data to arrive from the BS1. The
DEC modifier can accept up to 5 bytes, or until a terminator
character is received. There are a couple of ways to work it. On
the BS1, you can send a terminator:
SEROUT 0, T300, ( #45, 13 ) ' CR after data

or if the BS1 is always going to send two bytes, then the BS2 could
use the DEC2 modifier.
SERIN 0, 3313, 5000, nodata, [noparse][[/noparse]DEC2 databyte]

or, the BS1 could send one single byte, and the BS2 receive one byte:
SEROUT 0, T300, (45) ' BS1 send byte 45
SERIN 0, 3313, 5000, nodata, [noparse][[/noparse]databyte] ' BS2 receive byte 45
