I'm having similar problems getting PCSuite to recognize a connection with the phone. I am able to get a serial connection to the phone. Other services work (ftp, send by bluetooth). I do get a Windows reset every once in awhile when I try to reconnect the serial port. I will start up PcSuite and the icon in the lower right hand will show as unconnected (mRouter shows connected).
I have read in past posts to remove firewalls. Did this no change. I have Windows 2000 installed on this laptop. I am able to get this whole thing to work on my home XP system and PCSuite recognizes the serial connection. The Lotus app that I wish to sync with is on my work w2k machine and I need this to work. Any help would be appreciated.
