A few things I haven't yet done:
- As noted earlier, I haven't set up
dosemu yet, but I would like to
find out if this might offer a way to use the diskette drive indirectly while
Linux is running.
- I haven't figured out how to get the IrDA port working under Linux yet. The
only other IrDA-equipped device I have is an HP Laserjet 5MP, which seems
totally uninterested in whatever the Libretto might be transmitting from the
IrDA port. As an aside, getting this to work under Windows 95 is not
documented and is fairly tricky. Following Toshiba technical support's
recommendation, I moved the IrDa port from (COM2, IRQ3) to (COM3, IRQ4),
changing the other serial port from (COM1, IRQ4) to (COM2, IRQ3) to avoid a
conflict. Using the Windows Add New Hardware wizard with automatic searching
turned off, I added support for a generic IR device, which (under Windows) is
implemented as a pair of virtual ports (COM4 and LPT3). Having done this, I
installed my printer driver, specifying that the printer is attached to LPT3.
This works, but interferes with hibernation mode under Windows 95 for unknown
reasons (although hibernation mode under Linux continues to work properly).
The Linux/IR Project is working on an IrDA-compliant protocol stack for
Linux, which when completed will support networking between IrDA-equipped
computers as well as printing. Visit their web site,
http://www.cs.uit.no/~dagb/irda/irda.html, for further
- Modems and PPP or SLIP networking on the Libretto remain unexplored so
far. Both the stage 1 and the stage 2 kernels support PPP and SLIP (via
modules), so it should be possible to configure either service in the same way
as on any other Linux PC if you have the hardware. Under Windows 95, the
Libretto can be configured to turn off a PCMCIA modem when it is not in use,
which is highly desirable if you usually leave a modem in the PCMCIA slot.
These cards typically drain the battery rapidly and may cause overheating if
powered on for long periods. (The Libretto protects itself from damage with a
thermal sensor that shuts it down if it gets too hot.) For another alternative
to Ethernet networking, see Grant Taylor's Portable Computing with
