USB Modem dial-up disconnections

[Guest]

Hi all, I've realized an WinXP Embedded image for an industrial motherboard
with a Award Bios with PnP support, 512MB DOM (Disk On Module), DIMM 128 MB,
VIA C3 Processor (800MHz), VIA Twister-T chipset (82686B) and VIA 8606
integrates S3 Savage 2D/3D.

Due to remotely control these systems with a dial-up connection and UltraVNC
1.00RC18, I provide my systems to my customers with a plugged USB Modem like
as AVERYCOM or ATLANTIS A01-PU1. The system is the server and I'm the client.

In my image I've realized an incoming connection that works good (the modem
answer to my call).

When the dial-up connection in establisched and in the server there's a lot
of activity, like as an windows explorer opened where the operator move
rapidly the cursor in a very populated directory or an ours applications just
started, the dial-up connections is broke, without a valid reason. The
dial-up connection is lost in the client but in the sever the connection is
still up for a few second.

I've tryed to update the USB Modem Smartlink driver, to install VIA4in1 and
S3 Twister Driver, to install the USB VIA driver, change the telephone line
and change USB Modem.
The result is the same,

Can anyone help me?

Thanks a lot, Gionata

hi,
the golden rule is to test the same situation in full xp pro with the same
hardware configurations.

If in xp pro this works fine then you might be missing some component.

Hi Zen,

It's very difficult to install WinXP Pro on a 512MB DOM; I tryed to ghost
the same DOM image on a new 40GB HDD, the disconnection doesn't occur. The
dial-up connection works fine.

Is it possible that WinXp Embedded manage differently DOM and HDD? I forgot
some XPEmbedded component for DOM?

The used space in my ghost image is 404MB and the free space is 82.2MB.

Thank you all, Gionata
