K8061 by Ethernet

I assembled K8061 and it works OK !
Now I’d like to control it (and more then one) by LAN, so thougth to substutute USB I/F (Pic1) with a Tibbo EM202 (Ethernet/TTL I/F).
Is there any problem ?
Can you teach me about Pic1 and Pic2 communication protocol ?
Many, many thanks for answer

Interesting idea to control K8061 via the Ethernet. Indeed, the communication between PIC1 and PIC2 is in serial mode. The only problem to replace PIC1 with Tibbo EM202 is that the PIC communicates at 125000bps and the maximum speed ot the Tibbo EM202 is 115200bps. There is too big difference in speed.
