I am trying to implement a large send_sml()

Hi, thanks for issue report.

I'll look into this issue now. But I forgot python and this repository so it will take some time.

Best regards.

Tested.

secs.HsmsSsActiveCommunicator #send_sml short and long SML.
secs.Secs1OnTcpIpCommunicator #send_sml short and long SML.

Result: good. no problem. I suspected a failure in SECS-I message block division, but it turned out to be successful.

NOT test.

secs.Ses1OnPySerialCommunicator #send_sml

I don't have Serial-port PC. I use RaspberryPi to test SECS-I. I can't try it right away.

I also suspect a USB-Serial-Converter. SECS-I block send/receive requires 257 bytes of cache. Communication may fail with cheap ones. (I have also encountered.) I only buy FTDI chip USB-Serial-Converters.

Yes, I am using secs.Ses1OnPySerialCommunicator.

I will try better USB-serial-converter. And see if that helps. Thank you for testing! I will mark issue resolved.
