>I have a Duo 280c (System 7.5.5) and for some reason I couldn't get Zterm to
>work at all today.  It refused to believe there is a serial port on my 280c
>and only gave me an option: internal 19.2K modem.  The host PC I tried to
>connect with was Windows XP running Hyperterminal.  I had everything working
>before via serial port but today, no serial port.  I couldn't use modem to
>modem connection because for some reason my PC' 56K external has a hard time
>with the 19.2K modem and often would drop within a minute of establishing a
>connection.  I've tried disabling redundant protocol and resorted to
>connecting as low as 9600 bps without luck.

>Why couldn't the Zterm find the serial port?  I have no printer installed (I
>see a "null" on desktop though but not connected to anything) and Appletalk
>was turned off.  So by all account the serial port should have been
>available.  And it had been working before.  I hadn't changed any setting
>other than mouse speed in the control panel.

>I was trying to transfer a bunch of text files to my laptop for reading
>later (beside laptop is easier to use on bed than a 20 lbs PC and 19"
>monitor ^.^) and I don't have ethernet option for the Duo.  I ended up
>having to lug my recently mothballed Duo Dock and used it to transfer the
>files.

>PS the cable I was using came with my Quicktake 150 for Windows and it was
>perfect for PC to Mac serial connection which has 9 pin DB to 8 pin mini
>DIN.  An useful tip if you have such cable and frequently connect Mac to PC
>without wanting to mess with fussy network protocol or hard to find ethernet
>adapter or simply a quick and temporary solution.  Quicktake for Mac would
>have only 8 pin mini DIN at both end and not be useable for PC connection.

Can I see a LIST of Extensions and Control panels that are active.
The (Serial Built-in) extension comes to mind.
