tlug: Re: ftape with Trakker parallel port (fwd)

[Tony Laszlo <laszlo@example.com>]

TLuggers, 

I attached an IOMEGA parallel zip drive to the parallel port 
and insmod-ed ppa . I wasn't able to mount the thing (not 
going to use it, so am not worried about it), but could tell 
from the lines in /var/log/messages that it was being recognized. 
Hence, I think the problems I am having with the Trakker 
is a result of something other than parport and parport_pc.  

cat /proc/parport/0/irq  gives "7". 

cat /proc/parport/0/hardware gives :
base:   0x378
irq:    7
dma:    none
modes:  SPP
(want to change to EPP, but forgot which function key brings 
up the bios settings on this Aptiva 486DX ...)

 
/dev/ftape is linked to rft0
is this correct? 

I used ftape's default lines for Trakker in MCONFIG. 
Is this correct? 
 
TRAKKER_DEV=0
FDC_OPT +=      -DCONFIG_FT_FDC_PARPORT_$(TRAKKER_DEV)=-1 \
                -DCONFIG_FT_PAR_$(TRAKKER_DEV)=1 \
                -DCONFIG_FT_TRAKKER_$(TRAKKER_DEV)=1


After testing the zip drive, switching back to the 
tape drive (unplugging and plugging in the latter), 
I got different error messages in /var/log/messages . 
I thought it might work, but no such luck.

Any advice appreciated.
