I presume you are referring to the initial reported connect speed. The speed
of a connection can cange after the initisl negotiation and in cases like
this where you are not initally getting full speed, often does.

I don't think anybody really knows yet, at least not in the UK.

For that to happen somebody must have pretty much filled a large message
up with spaces, or something similarly redundant. Normal text articles such
as this one compress at generally between 2:1 and 2.5:1 under V.42bis.
You're right though that standard PC serial ports can only be set up to
115200bps.
