The background is I'm trying to get parallel port access using VMware on
a Red Hat 9 linux system.
The hardware is an IBM T21 laptop. It has a parallel port, recognized
and working fine in Windows.
VMware wants an ECP port to allow two-way communication between programs
running in the VMware session and the outside world. There is an option
in the BIOS to set the port to ECP Mode.
After booting into Linux, I can do this:
[bret@ganesha learning]$ cat /proc/sys/dev/parport/parport0/base-addr
[bret@ganesha learning]$ cat /proc/sys/dev/parport/parport0/irq
[bret@ganesha learning]$ cat /proc/sys/dev/parport/parport0/dma
[bret@ganesha learning]$ cat /proc/sys/dev/parport/parport0/modes
The first three settings correspond to the settings in the BIOS. I'm
not sure about the last.
There are other settings for the port mode, with other responses:
Output Only PCSPP
Should the response for ECP be PCSPP,TRISTATE,ECP? It's not, and VMware
reports on start-up that the parallel port doesn't support ECP mode and
won't be used.
Thanks in advance,
