LPTDRV is a memory resident driver for LPT network.
It hooks IRQ 0 and checks ca. 18 times per second LPT status.
If any activity found it reads and decodes recieved data,
and stores it into its 5000 bytes input buffer. It has also
5000 bytes output buffer for sending data.
Applications can communicate with this driver by INT 63h.
see LPTDRV.ASM for more details.


Parallel printer port pins 14, 17, 18
must be connected on both computers directly, eg. one to one.

pin 14 carries syncronisation signal. 0 1 0 1 0 1 ...
pin 17 is used for data input/output.
pin 18 is ground.

Maximum transfer speed on my computer was ~ 12 Kb/s.
