 The newer Courier HST's can transfer data at 14.4 kbps - without fancy
MNP compression. Transmitting ASCII files with MNP compression turned on
you can get up to 2300 cps throughput (this is not from hearsay - I have
seen these numbers every day under real-world conditions). That's why
you can set the HST to 38.4 kBaud.
 But there's a drawback: You must have drivers and hardware that can
stand receiving data at 2500 cps and that can do real hardware handshake
(RTS/CTS), and finally a protocol that doesn't overflow the reverse channel
which runs at 450 bps. Zmodem, for example, will work fine.

I am using a Miracom Courier HST DS, which is the UK version of the
US Robotics product. I am moving to Australia next year and I wondered if
anyone knew whether this modem would work correctly there. I know that this
modem is different from the US one as I tried a US one and it recognised
the UK ringing tone as a busy tone.

Alternatively does anyone know if US Robotics have a subsiduary in
Australia, and does anyone have a contact address/phone number?
