I'd like to move my Optimum teletext adaptor from a DOS box to a Linux
box. One minor problem is the lack of a device driver. Optimum
Technology say that they don't have drivers for any flavour except Unix
and that they aren't willing to give me any interface spec. They did
offer to upgrade me to an external unit which communicates via serial
port but that is not an option I'd like to use.

So.... has anyone written a device driver for this beast? If not, I'd
welcome suggestions for PD PC disassemblers so that I can reverse
engineer their 4.5k driver and write my own.

Regards,

Mark.

Another approach may be to leave the card in the DOS box and somehow
access it from the Linux box. The card has a driver which creates a
device called "OPTIMUM3" which can be used to access the teletext
adaptor as if it was a file. Is there a way to access this file via
TCP/IP?

I'm running Microsoft TCP/IP on the DOS box and mount some network
drives from the Linux box using Samba. Is there a way to do the reverse,
either to share a DOS drive or maybe just the device? I've seen the
FTP-like Samba client but (unsurprisingly) can't see a way to use this
to access a remote device read-write.

Ideas?

Regards,

Mark.
