Please can someone confirm the Hilo3G doesn’t support the multiplexer mode (-\> AT command CMUX) ? I would like to use the GSM 07.10 Multiplexer Protocol but I’m afraid the Hilo3G is not compatible with it…  
Thanks.

Hi  
As per AT command guide, seems like CMUX is not suppored in Hilo3G. Anyway I’ll check it internally once…
