Fetching signal quality during data connection?

[colin.helliwell at ln-systems.com]

I've not had any luck yet talking direct to the serial port instead of my mux driver. I think (judging from a scope) that the problem may be that the baud rate isn't in sync between MM and modem/port - does MM set the baud rate on start-up, or make any assumption about what the port/modem is using?
By the way, is there a way to prevent MM trying selected plugins on a port?

I've not yet been able to establish how the modem really behaves, but it may be a complication of the mux driver that I'm using MM on. So I'll try removing that and talking direct to the real serial port.
