Hi guys... my two cents worth on the topic... Some of you may know about my 64HDD project... the next on the list is USB64 which would hope to add such features.... http://pages.hotbot.com/family/coplin/c64-proj.html The concept I propose adopting is that the PC which hosts the software/hardware is responsible for everything allowing standard DOS networking drivers to do all the work... The CBM machine knows (or cares) nothing about this unless it needs to... other ethernet machines send/receive data from the "USB64" box without the CBM doing anything (all done in the PC box)... when the CBM needs data it gets it via the IEC serial link using by openning a channel and using get# (or put# to send....) The USB64 box can handle responses to being Pinged etc.... and hold-off other internet requests until the CBM has chosen to communicate.... Anyway... all theory at the moment.... but in my way of thinking it would save a lot of trouble on the CBM interfacing and protocol support.... it also means any Ethernet card with a DOS driver would work. - Nick > -----Original Message----- > From: Richard Atkinson [SMTP:Richard.Atkinson@cl.cam.ac.uk] > Sent: Thursday, 20 July 2000 21:44 > To: cbm-hackers@dot.tcm.hut.fi > Subject: Ethernet > > Anyone following comp.sys.cbm will have seen a recent thread on Commodore > networking.
