Windows 10:
smstools3-3.1.21:
Smsd installed from: smstools3-3.1.21.tar.gz
2N VoiceBlue next :
Interface: Telnet

I am trying to send sms through Voice Blue next modules which apparently need prefix at&g0 to select 1 of the 4 modems.
How can I configure smsd to use this prefix.

Smstools does not support those kind of prefixes. Each modem must produce its own serial interface.
