Hi,

I don't mean to be a pest, but the following message that I posted a couple of days ago hasn't attracted much interest.  I'm sorry it's so long.  I really would be grateful if someone who knows the answers to the questions at the end could try to help.  Thanks very much!

The documentation says that this modem has a built in 16550 UART and a programmable flash rom DSP, which are the parts that I thought were "missing" from the PC-Tel modem.  As Mike Pelley suggested, I looked at pcidevs, which has vendor code 0x11c1 for AT&T Microelectronics and almost fifty lines of product numbers for LTMODEM devices.

The significantly increased performace together with what I thought were enough chips and finding AT&T LTMODEM in pcidevs raised my hopes that the Zoom modem would work on NetBSD.
