[ILUG] Modem question

[ILUG] Modem question

	I think I asked this before and the answer (from Paul Kelly)
	was you can't do this generically because the modem can
	change speeds mid call (retrain). Also there is no standard
	AT command to get the current speed IIRC. In summary windows
	is (sometimes?) lying when it reports the connection speed?

	Pádraig.

Nah,
	Modem speed, as reported, is usually what the modem reported in the
'CONNECT 38400' or whatever line when the dialup happened ... it's _very_
unusual for a modem to retrain mid-call (the main exception being GSM HSCSD
modems)
	The connection speed reported by the modem will be either the DCE or
the DTE speed depending on the initilisation settings (and the value of the
S95 register on rockwell based modems). This can be what people mean when
they say that the modem is lying, telling them it's CONNECT 115200 rather
than CONNECT 2400 <g>
