InpOut32 for PellesC

have you tried to disable the FIFO settings in "advanced port setting" ?
just slide completely to the left or uncheck the option, if there is a checkbox.

Ummm... I hadn't thought of that, but what effect would this have?  
(aside from the obvious disabling of the on-chip buffers, that is)

sometimes it works afterwards

... The best thing is to find another driver, thanks for your input...

if they are from M$, named
serenum.sys and
serial.sys
and have a description which correlates to the installed XP Sservice pack
(here i have XP SP2 and the drivers are of version (xpsp_sp2_rtm.040803-2158))
then let them as they are!

interesting, i have both drivers from the same version,
maybe this produces troubles at your side.

It's strange that both the Device Manager and DELL diagnostics say the port is ok. Btw, on my old machine where COM1 is not working with the termial app and COM 2 does work, both ports have FIFO enabled.

I'll forget it for now, there does not seem to be an obvious solution.

It does seem a little odd.  These days the comports are integrated into the chipsets, seems to me that if one works both should... and it's really odd that you have two machines and the same problem on both.

If you ever do get it sorted can you let us know what you did...  Might be handy info at some point in time.
