[...] When connecting multiple modems to a pc and start communicatin with them the connection gets broken and the log file gets full of the following messages: [...] option: option_instat_callback: error -71 option: option_instat_callback: error -71 option: option_instat_callback: error -71 [...]
I forgot to mention that the errors: Aug 26 11:49:30 localhost kernel: option: option_instat_callback: error -32 Aug 26 11:49:31 localhost kernel: option: option_instat_callback: error -32 Aug 26 11:49:38 localhost kernel: option: option_instat_callback: error -32 Aug 26 11:49:39 localhost kernel: option: option_instat_callback: error -32 Are also pretty common. The error is pretty easy to reproduce:I just need to connect the modems to a pc and open the ttyUSBX port using minicom.
A few minutes later I can not send any AT commands to the modem any more, neigther I can receive the preriodical updates from the modem.
Thank you, Artem
