Well, the vast majority of them don't support V.42, so I guess maybe it's time to send for some new roms... 8-) BTW, looking at your addendum, did they add support for a 38.4 KBPS interface rate? If not, then it's going to be real hard to get a 4X performance boost at 9600 BPS, eh? -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)
