Syncing on jpilot

I'm trying to get help on syncing my Treo 350 using jpilot running on SuSe 9.1 
Pro.  The error message I get is this:

Syncing on device /dev/ttyS0
Press the HotSync button now 
********************************
pi_bind invalid argument
Check your serial port and settings
Exiting with status SYNC_ERROR_BIND
Finished.

This is new problem for me.  I used jpilot successfully for months.  However, 
this past weekend, I needed, for the first time, to try to configure my 
external modem for a dial-up internet connection.  To do that, I used the 
same serial port that I otherwise use for jpilot.  Not only was I 
unsuccessful in configuring the modem, but afterwards, when I tried to sync, 
this error message appeared.  

I've since deleted the modem settings, but that does not help.  Can anyone 
explain what the message means, and what I can try to fix it.  I'm afraid 
that I have to admit to being a relative newbie, so I need the instructions 
in baby steps.

Thanks.
