This excerpt, from an EvangeList post of 09/28/1998, says - in part- that
the answer might depend on which model of PowerBook you're using:
====
The Apple Tech Info library contains at least two articles generally
describing the capabilities of infrared-enabled Macs. These are Article
ID 58012, dated 8/13/98 and modified 8/24/98, and Article ID 20928, dated
2/6/97 and updated 8/24/98.
The big picture is that not all infrared-enabled Macs are created equal.
Powerbook 190, 5300 and 1400 models are infrared-enabled, but not irDA
(Infrared Data Association) compliant. They "speak" irTalk. The infrared
implementation used in these PowerBook computers is designed to share
information with other infrared-equipped PowerBook computers and the
Farallon Air Dock (a wireless LocalTalk filesharing solution). The Apple
IR File Exchange transfer rate is 230.4kbs, the same as LocalTalk.
On the other hand, the iMac and Powerbook 3400 are irDA compliant. That
means that, in principle, they can converse with any other irDA compliant
device. In practice, though, what is supported in the hardware may not be
supported in software. For example, PowerBook 3400 computers have the
hardware necessary to communicate with the IrDA compliant Apple eMate 300
and the Newton MessagePad 2000. At this time Apple does not have a
software solution to communicate with the Newton 2000 and eMate 300
through IrDA. As my original article stated, though, it is easy to build
a quick wireless short-range Ethernet network using infrared between a
Powerbook 3400 and an iMac.
Powerbook 3400s also have the option to switch to the IRTalk protocol by
using the Infrared Control Panel. PowerBook 3400 computers can therefore
communicate with other IRTalk-capable devices (such as 190, 5300 and 1400
PowerBooks) using the IRTalk protocol, but not the more standard irDA.
=====
The post also has a description of how to get a PowerBook 3400 to talk with
an iMac, but since that doesn't seem to relate to your question, I left
that bit out. However, if you *do* want the full post, please let me know.
