As a preliminary step to reading RFID data I set up a Duinomite Mega and am sending it a data stream from an Arduino at 9600.
I would like this data to be read by the DM and printed to the screen.

Have used
OPEN "COM2:9600" AS #1
PRINT #1, "13"

Nothing happened. Seems a bit naive but this what I came up with after some hours of combing through the posts here and there. RTFM, at least the appropriate bits.(I hope)
I have the TX from the Arduino attached to pin 13 on the DM (this should be the RX pin).

I am running MM-4.0002 for the DM

Tested this successfully running 2 Arduinos TX to RX.
This is of course at TTL levels
The code for the RX Arduino is

void setup()
{
// initialize the serial communication:
Serial.begin(9600);
}
void loop() {
byte incoming;
// check if data has been sent
if (Serial.available()) {
incoming = Serial.read();
Serial.print(incoming);
}
}

Converted to MM Basic this would be ?
Any help on this would be much appreciated.

Hi Pelargic,

I think you would need to do this

OPEN "COM2:9600" AS #1
INPUT #1, A$
Print A$

Mick

Thanks for that Mick, unfortunately this and other ideas have failed to hit pay dirt.
I saw that there may be a bug in INPUT() and so tried a couple of similar workarounds without result.
I will try this again later when I get a Maximite.

Do you need to invert the serial data?
I am not familiar with the Arduino signal levels but it might be necessary to put a simple one transistor inverter in the RX line.
