IRCOMM Tx and Rx Thread Priorities Are Not Set Correctly (290490)


The information in this article applies to:

  • Microsoft Windows CE 3.0 for the Handheld PC 2000
This article was previously published under Q290490

SYMPTOMS

RasDial may not work because Unimodem reads partial responses, which causes it not to pass the connection attempt. For example, on a direct cable connect, Unimodem sends "CLIENT" and expects back "CLIENTSERVER". On the problem device, only "CLIENTSERVE" is returned in the first ReadFile. A subsequent ReadFile returns "R", but this is too late for Unimodem.

CAUSE

IRCOMM has a configurable thread priority base for its Tx and Rx threads, but it does not correctly set the priorities for the two threads. When IRCOMM's threads run at their proper priority, full responses can be returned to Unimodem.

RESOLUTION

A supported software update is now available from Microsoft as Windows CE 3.0 Core OS QFE 25. To resolve this problem immediately, click the following article number for information about obtaining Windows CE Platform Builder and core operating system software updates:
