     Has anyone implemented a driver for a BIDIRECTIONAL parallel port?
(The standard printer interface is output-only.)  I need 8-bit parallel
data transfer in both directions but on separate lines with appropriate
handshake lines.  Data rate will be very slow, under 100 bytes/sec.
I'd like to use some low-cost off-the-shelf VMEbus card, such as the 
Motorola offering.  Anybody done this yet?  I hate writing drivers.

The only I/O supported by the robot software is parallel.)
