SYMPTOMS

If you attach your Handheld PC (H/PC) and another serial device to a serial switch box connected to your desktop computer, Windows-based programs may be unable to use the serial device.

RESOLUTION

To resolve this behavior, start and then stop Microsoft ActiveSync Service Manager.

NOTE: Communications (COM) ports that are in use when you start ActiveSync Service Manager are reset. For example, if you are connected to your Internet service provider (ISP) using a modem on a different COM port, the modem is disconnected from your ISP when you start ActiveSync Service Manager.
