Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello,

Sorry, but the time I got registered on that forum, I fixed my problem.

A Duinomite is receiving the data send by my energy meter. The serial port configuration is 1200 bps, 7 bits, even, 1 stop bit and can't be changed...

It is not possible to declare something like :
OPEN "COM3:1200E7" AS #1
which is done straightforwardly by terminal programs.

The port is open as 1200, 8 bits, no parity and 1 stop bit.
The trick is to get a character at a time and to remove the parity bit.


OPEN "COM3:1200" AS #1
...
Rcd:
A$ = INPUT$(1, #1)
IF A$="" THEN GOTO Rdc

A = (ASC(A$) AND &h7F)
A$ = CHR$(A)


I hope it will help someone!
