Odd. Maybe the port isn't clocked at the usual frequency, and 115200 is the wrong base. > 'User Manual' supplied with the card says that I should use > 'Automatic Crystal Detection' in WinME and '1.8432 MHz' in 2K/XP. Well, 1.8432MHz corresponds with a base of 115200, so that's not wrong. IS your modem showing the DTE speed in that connect line? If so, 2400 baud seems to actually correspond with 230400 baud, which would be a rather interesting state of affairs.
