Modbus RTU - CRC delay

[Ababuy78]

I am observing a 500ms delay between any read command (FC1, FC2, FC3 or FC4) and its respective CRC.

Is this behaviour expected? It seems odd.

hi, thank you for the issue, can you find more information and fix if needed ?

[Ababuy78]

I could try, but I am not proficient at javascript so it would require an unnecessary large amount of time to immerse my self on this project to find the issue and correct it.
I would prefer if someone familiarized with the project to correct this issue. Is that ok?

Sure, I added a "help wanted" label, It will let people know that can look at this issue and comment if they have more information, or find a fix.

thank you again for noticing this issue and reporting it 💚

HI, I want check a question
Are you using modbus-serial self-host a ModbusRTU Slave?

[Ababuy78]

Hello!
No, I was using an external emulator.
As I could not see any problem with the modbus-serial library I connected directly to a PLC and the problem was solved.
It seems that the issue was using the same machine to test everything with a serial port emulator in the middle.
I believe this issue can be closed.
Thank you!
