According to my experience unless you know 1) the exact model of modem, 2) the options that have been set in the DIP and/or memory switches and 3) what kind of speed you are connecting at ... best make no assumptions about what a modem is going to do. If you know those things, the results are totally predictable but without them, you don't know if the speed indicated is the speed of 1) the link between the modems, 2) the speed of the port. To know what the speed of the DTE should be you need to know if the modem set to lock the speed to the port or not, and, if so, under what conditions. Even when you have that all figured out, there are sometimes significant differences between two modems with from the same of the same make and model but with different serial numbers. Fun, huh?
