Hi,

I'm printing text to a LCD 1602 with [print( messages through [comport], and a message takes about 2 seconds to appear on the LCD, when it's seemingly instentaneous from the Arduino serial console. Why is that? (I'm on lubuntu 18.04)

For the moment what I do is print with a command through [shell]

echo "Hello!" > /dev/ttyACM0

Which works nicely.

@allister I would expect the message to go through or not. A delay is strange. Maybe it is waiting for a stop bit.... and then times out?
Maybe try sending your message through the [comport-help] patch and match the settings to the arduino.
It has all the possible commands available to try and to play with.
Apparently sending data too fast can cause this...... so maybe reduce the baud rate (for Tx and Rx).
David.
