adamg:
I have no such a modem, but I took a look at smsd behaviour during telnet negotiation using netcat as a telnet server and I see that smsd continuously sends telnet_login if there is no enough delay between login and password prompt.
So the session looks like:
smsd> AT
telnet> login:
smsd> <telnet_login>
telnet> Password:
smsd> <telnet_login>
telnet> anything else
smsd> <telnet_login>
Hi,
I've applied the full patch that you included below this, and I'm still getting this same behaviour (smsd is continually re-sending the username....)

I'm using a portech MV-370.
My config file has this:
[portechmv370]
device = @X.X.X.X:23
telnet_crlf = yes
telnet_login = voip
telnet_password = 1234
telnet_login_prompt = username:
telnet_password_prompt = password:
telnet_cmd_prompt = module1, module2, state1, state2, info.
telnet_cmd = module1
init = ATV1
The log file shows this:
2012-03-16 16:59:49,5, portechmv370: Modem handler 0 has started. PID: 20314. Will only send messages.
2012-03-16 16:59:49,6, portechmv370: Checking if modem is ready

Any assistance or hints that you can offer would be greatly appreciated.
