I've routerOS v4.6 on x86 platform.
I've attached huawei e1550 gsm modem to usb. It seems to me that mikrotik recognize it.

But when I try
/tool sms send usb2 "123456789" message="Test!"

it says
action timed out - try again, if error continues contact MikroTik support and se
nd a supout file (13)

where can be problem ?

on v3.26 error is :

failure: +CMS ERROR: 500 (unknown error)

i have the same problem. it works on v3.20 but there is no inbox

so any sugestion why it works on v3.20 and not on 4.6 ?

Thanks

Tom
