Hello Henk,

I already tested it with a Baud rate of 38600, without good result.

After I read your answer I made the test with 9600. Everything is working fine now.

Thank you for the support.

Regards, Pascal.

Hello Pascal,

You can try to set the 'FlowControl' property in the 'Advanced' settings of the GSM Modem Gateway to another value. Decreasing the baudrate of the serial port in the 'GSM modem' settings might also help.

If changing these properties does not solve the problem then there is not much else you can try in Diafaan SMS Server to get rid of this error.

Regards, Henk

Setup 1:
Diafaan Light on a Hardware machine.
USB to COM – MOXA Uport 1100
GSM Modem – MOXA Oncel G2111

Everything is working fine.

Setup 2:
Diafaan Light on a VMware® Workstation 12 Player (12.1.1 build-3770994).
USB to COM – MOXA Uport 1100
GSM Modem – MOXA Oncel G2111

Troubles with the connection to the GSM modem (see Log file).

2017/06/13 13:31:11.920 - COM7: A character-buffer overrun has occurred. The next character is lost

How can we solve this trouble?

Best regards.
