i would get rid of the cariage returns and write my code to wait for the ack
so
BUTTON_EVENT [dvTP,3]//Multiple Strings One Carriage REturns
{
Push:
{
SEND_STRING dvSamsungDLP,"$08,$01,$00,$00,$00,$00,$E6"
SEND_STRING dvSamsungDLP,"$08,$02,$00,$00,$00,$00,$E5"
SEND_STRING dvSamsungDLP,"$08,$03,$00,$00,$00,$00,$E4"
SEND_STRING dvSamsungDLP,"$04,$12,$00,$D9,$0D"
}
}


BUTTON_EVENT [dvTP,3]//Multiple Strings One Carriage REturns
{
Push:
{
SEND_STRING dvSamsungDLP,"$08,$01,$00,$00,$00,$00,$E6"
Wait_until(sam_buffer="'$03,$0C,$F1'")
{
clear_buffer,sam_buffer
SEND_STRING dvSamsungDLP,"$08,$02,$00,$00,$00,$00,$E5"
Wait_until(sam_buffer="'$03,$0C,$F1'")
{
clear_buffer,sam_buffer
SEND_STRING dvSamsungDLP,"$08,$03,$00,$00,$00,$00,$E4"
Wait_until(sam_buffer="'$03,$0C,$F1'")
{
clear_buffer,sam_buffer
SEND_STRING dvSamsungDLP,"$04,$12,$00,$D9,$0D"
}
}
}
}
}

I hate the fact that you cant use any code formatting on this site argh
