ve just had ISDN installed and have a Zyxel omni.net USB ISDN "modem". On my PB G3 running OS 9.1 everything works fine but on my old PowerMac (200 Mhz, 603e chip) with OS 8.6 and a PCI USB card I can connect but as soon as I start accessing a web site (using IE 5.0 or Navigator 4.7) I lose the connection (usually with the message "try +++ escape call clearing"). The fact that I occasionally succeed in downloading one (non-cached) page indicates that the software and hardware can work, for a minute or two at least. The USB card works fine with a CD burner and scanner. I can't upgrade the PM200 to OS 9 because that came bundled with the PB G3 and is machine specific. Anybody know a fix?? Thanks!!
