hi All...

Have played with my code a little more....

Have come to conclusion that the serial port is seeing 0xFf before I type any password... I found by putting a 232 sniffer on the ports !!!


Ie the password is 9 chars but the first on occasionally is 0xFF ????

any Ideas ? anyone ?

Tomorrow O will go back to Serin / Serout see how that gets on !

Thank you for help !

For reliable communications, I always clear the receive buffer before transmitting a request to any perif. That way if you have some noise on the comm lines, it won't be interpreted as bad data.

Hi Dave

Sounds good.... But how do I do that ?

I see no pointers in the manual V2.60

THank you for help

MY Defines are now :-

DEFINE HSER_RCSTA 90H 'Set receive status and control
DEFINE HSER_TXSTA 24H 'Set transmit status and control
DEFINE HSER_BAUD 9615 'Baud Rate
DEFINE HSER_CLROERR 1 ' Clear Buffer

Andy,

You can always just use a "HSERIN" bogus statement to throw away anything in the buffer before you execute your regular "HSERIN" statements.
Since the EUSART has a 2 byte buffer you may need to do two of the bogus "HSERIN" statements with timeouts just to make sure you don't get stuck waiting.

Hi

I just put your suggestion in place and it seems to be working for me .... I just used 50 as a time out figure... thank you!

I will try the other suggestions also thank you as always Henrik

For now I need sleep !!!!!
