We recently moved our Courier ISDN modem from a Windows XP machine to a Windows 2000 Pro computer which we did a clean setup on in order to use as an office proxy server.
The Courier ISDN serial port modem (US Robotics part 000698-13) worked fine on the XP machine. However, on Windows 2000 I can't get it to activate and use the B channel, effectively limiting my bandwidth to 64k.
Following US Robotic's tech support advice, we have upgraded the modem's firmware to the most current version. Still no luck, and now USR tells me it's an operating system issue and won't provide any more help. I paid premium bucks to get a US Robotics product and to say I'm disappointed with their tech support is an understatement.
Anyone experience anything like this? 128k isn't fast, but 64k is barely tolerable!
Thanks in advance... Park
