What sort of UART do you have?  To run above 9600 you really need a 
16550, if you have an 8250 or 16450 you'll get lost characters.

Your problem with file downloads etc is most likely caused by the 
numerous retries required when you start losing characters.

If your modem is using compression, set your COM port speed to
signifcantly something higher than the line speed, e.g. for 14.4k, set 
the COM port to 38.4k.

Hope this helps,

Regards,
