Anyone know how to detect if a serial virtual driver is installed and present? I'm using SrmOpen to connect to a vertual driver. All works fine when the driver is installed. When the driver is deleted, the call succedes but communications fails. If the driver has not been installed since a reset, SrmOpen fails. I would like to detect if the driver is installed and present on the hand held so I can provide proper feedback to the user (and reduce my tech support). I've tried DmFindDatabase which seems to always return an ID > 0 even when the driver is not installed. I've tried SrmGetDeviceInfo, which seems to never fail when attempting to find the virtual driver ID. Any ideas?
Thanks Dave I did post a similar question in the Comm forum but traffic there seems to be light today. Just in case: CW8+patch SDK5 OS 3.5.2 device -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
