The Serial Port probe prevents attached modems going off-hook at first attempt. This problem was noticed with diald where the first connect attempt after boot would consistently fail. Subsequent connect attempts were ok. The solution I adopted was to add the -s option to the kudzu commandline in /etc/rc.d/init.d/kudzu. Perhaps more work needs to be done to ensure that the UART is left in the same state after the probe as it was before.
Are you using the updated pppd & initscripts? There was a double-dial problem with those...
The packages in use are: initscripts-4.70-1 ppp-2.3.10-3 I check for updates weekly and install as appropriate.
What sorts of modems?
(and what are they detected as, if anything, in /etc/sysconfig/hwconf?)
