Summary:
When sending a serial command that contains a NUL, Hex 00, from the serial port of the N2600 the command stops at the NUL.
E.G. If you send 31 32 31 33 31 34 the N2600 will send 121314 from the com port as expected; but if you send 31 32 33 00 34 35 36 the N2600 com port will only send 123. The command is stopped at the 00.
Troubleshooting:
Issue fixed in firmware v2.0.8 or higher.
