There is no way a serial (COM) port connected modem can be a WinModem. The only way an external modem could be a WinModem is if it's a USB modem. It is always possible that it does not use the "standard" Hayes AT command set, but, if you have or can get the command set, it will still work with FreeBSD. I can't imagine any modem less than 5 years old that does not use AT commands, so I suspect some other problem, line a connection to a non-functional port or not having BIOS configured properly. Does another modem work on this port? Does the port probe properly? (Check dmesg for sio0 (COM1) and sio1 (COM2). They should probe as a 16550 or 16550A. If they probe as an 8250, they are most likely not working as no reasonably modern system will have an 8250 UART. (It turns out that the driver test for modem type gets no response from an 8250, so 8250 really means "no response".) If you see a message about the irq, you probably have a BIOS problem. R.
