I apologise in advance for the long message, but I'd like to avoid giving
misleading information or ambigous context in my questions.
I am trying to use a PalmIII with Win4Lin on my IBM 770ED Thinkpad
notebook, but have not been able to get this configuration working.
I *have* read all the documentation, knowledge-base answers, and Win4Lin
mailing list archives covering the areas of: serial ports, palm pilots,
dos/win device configuration.
I'll admit now that my MS-Windows experience is *MUCH* less than my
Unix/Linux experience, but have had no real problems with configuring
Win4Lin until now. I had earlier backed up my /var/win4lin and $HOME/win
directories, and after each of the unsuccesful changes, I reverted the
installation to a fully working state (without serial support).
The Thinkpad claims com1 (io=0x3f8-0x3ff, irq=4 --> /dev/ttyS0) for its
InfraRed port, and I need to be able to use that port as well, so I don't
have the option of disabling the port (I have been testing this
installation with the IR port configured, but not in use).
When I modprobe the serial.o module, the first detected port is com3
(io=0x3e8-0x3ef, irq=4 --> /dev/ttyS2).
I have verified that this port is functioning under linux, by doing:
cat /dev/ttyS2
then using the palm (Symbol Palm 1500), I run the "serial port test" in
the in the Diagnostics application. I can see the data sent ("This is a
test.") by the palm in the linux console running 'cat'.
I realise (correct english spelling) that there may be a problem with irq
conflicts due to both devices using the same interupt, however, linux
seems very happy to allocate it. I have also tried using 'setserial' to
manually reconfigure com3 to use irq 3 -- it worked in linux, but it made
no difference to Win4Lin.
I have installed (correctly I believe) the Windows side of the serial port
device, and all attempts reading/writing Com3 (direct, virtual), and Com1
(direct remapped) have failed with an error like "incorrect file
permissions on device". (I'll redo that configuration if anyone needs the
exact error - sorry). As per the knowledge-base answers, I did change the
permissions on the (/dev and /var/win4lin/mrgdev -- all permutations)
devices to 0777, but no prize.
I have tried experimenting with the "Custom" class of devices in "Device
Definition", adding via both "Direct attach" and "Virtual attach". I've
tried all of this with and without the serial.o module loaded (just in
case some Win4Lin kernel code prefers to allocate the irq's etc).
I've tried removing the Com1 and Com2 tokens, then creating a "direct
attatchment" with "irq 4" remapped to "irq 4", and "io port 0x3e8-0x3ef"
remapped to "io port 0x3f8-0x3ff). Result: "ERROR: Could not allocate
interrupt vector 4"
I've tried creating character special devices (using mknod) for com3/4
under /var/win4lin/mrgdev/vpi and /var/win4lin/mrgdev/ppi (so that their
entries follow the major/minor device sequence, and so that they have the
same naming conventions and file permissions).
I'm at the end of what I can do myself without some sort of interface
documentation for the Win4Lin kernel modules... hell I'll even write my
own kernel modules if it will alleviate this problem, but I hold no hope
of ever seeing that documentation, as the Win4Lin kernel modules,
replacement windows executables, drivers and dlls are the sum total of the
Trelos's/Netraverse's intellectual property (that I can see from mu
perhaps limited perspective) in the Win4Lin product.
I'm now becoming desparate, and would apreciate *ANY* help I can find from
this list.

PS: Another, non-urgent matter (maybe for the kernel mailing list): does
anyone know to transparently redirect serial ports to TCP/IP sockets in
both Linux and Windows? I am working on a product which has serial
communications occuring between a PalmOS application and a Win32 program.
(It does work in windows, but my laptop is a single-boot linux box, and
thats how it will stay.) So I would like to try having the Win32 program
running under Win4lin talk directly to the PalmOS application running
under the Palm Pilot emulator (poser) -- any ideas?
