ERROR : Device Com1: is not available
Running under XP. dbase 4 ver 2 or dBase 5.

I have disable all startup items in MSCONFIG and startup directory.
Win98 no issue.
The pc being is a dual boot this will indicate the ports are working.
I need a solution with in two weeks earlier the better.

Paul.

COM1 NOT available
This is often because you have another device that has access to COM1 and has priority over it compared to your dBASE DOS program. This is normally a modem. You can do two things:
EITHER run your dBASE program against COM2 - and check whether XP has re-allocated your physical Serial Port to COM2 having taken COM1 for the modem
OR remove the modem card for now just to check that it isn't taking priority - or realloacte the modem to another COM port - say COM2.
Remember COM1 and COM3 are effectively the same (as is COM2 and COM4) so you really can only work with two ports at a time.
Hope this helps.
