serin or debugin items

[iw2fvo]

good dat to all of you in the forum!

> I will like to understand if the "timeout " set in the serin or debugin refers to a NO received signals ( or line set to 0Vdc ) or at any kind of signals received ( noise for example ).
If noise is received, does the timeout trigger and send my program to a particular label ?

> can I set a timeout and a "string " after which the received data is stored ?
What will be the correct syntax '

Thanks for any assistance

Timeout only works for a noise free line in the idle state. If the line is in the opposite state timeout is skipped. Likewise if the line has noise, that will be seen as data and never get to the end of the timeout period.

Hi, BrianT:

probably you will be able to help me on this item:

I wrote a small program that reads some bytes of data coming from a radio receiver module. I do not want that the receiver program gets stuck in case the transmitter goes off for some reason. The receiver program is this :

SERIN PORTB.0,N1200,["COUNT"],W
SERIN PORTB.0,N1200,["ST0"],S_T.BYTE0
SERIN PORTB.0,N1200,["ST1"],S_T.BYTE1
SERIN PORTB.0,N1200,["SRH0"],S_RH.BYTE0
SERIN PORTB.0,N1200,["SRH1"],S_RH.BYTE1
SERIN PORTB.0,N1200,["WIND"],WND
SERIN PORTB.0,N1200,["IRR0"],IRR.BYTE0
SERIN PORTB.0,N1200,["IRR1"],IRR.BYTE1
SERIN PORTB.0,N1200,["VBAT0"],V_BATT.BYTE0
SERIN PORTB.0,N1200,["VBAT1"],V_BATT.BYTE1

If the transmitter goes off then the receiver locks up waiting for the "STRING". How could I overcome this problem ?

Thanks a lot for any help on the matter.
