They really should have given us 28.8
I have to admit that 14.4 Kbps (V.32 bis) is adequate but it's too bad
the Butterfly doesn't have 28.8 (V.34) builtin. (Of course the ThinkPad 560 has no builtin modem!)
The Butterfly's modem is DSP-based but unfortunately, it's not the
MWave version that newer ThinkPad's such as 755 have so it is not
Note that the Butterfly only ships with a modem in the US and Canada.
This is because the modem is not approved for use in other countries.
Export versions are built without the modem electronics and jack.
Here's the Butterfly internal modem
config I use.
You can look at your config modem's using the "AT&V" command.
US Robotics Courier
I have a Courier
V.Everything PCMCIA modem.
Here's the config I use.
You can look at your config modem's using the "ATI5" command.
I run my Courier at:
To use the Courier, you must disable the internal ThinkPad modem in
the bios menu and also in the Windows 95 device manager.
To install the Courier under Windows 95, you need to fetch
from the US Robotics
ftp site and copy it to c:\windows\inf.
The folks at C/Net liked it in their
modem performance review.
Fax under Unix
Once nice package is
HylaFAX. It's standard under BSD/OS.
Avoid the XJACK connector
One type of pcmcia modem you should stay away are the ones with the
XJACK connector; the Butterfly keyboard gets in the way, especially
when you try to use the modem in the top slot. Most if not all
USR/Megahertz XJACK modems also come in the dongle flavor, so this
shouldn't be a big problem if you haven't bought a pcmcia modem yet.
