I've seen situations where a certain sequence of characters will cause 
some modems to hang up.  Is it a bug is someone's chipset?  Almost 
certainly.  Can you do anything about it?  That all depends on the 
hardware.  Sometimes, however, it's something a lot more simple:  flow 
control.

Add these lines to your pppd options (on the command line, or in 
/etc/ppp/options):

asyncmap a0000
escape 11,13

This will tell your pppd to encode sent XON/XOFF characters, and will 
tell it to negotiate with the other end to do the same.

Split for readability only:

current release=security host=sup.netbsd.org hostbase=/ftp/pub base=/usr
	prefix=/usr backup use-rel-suffix delete
current release=doc host=sup.netbsd.org hostbase=/ftp/pub base=/usr
	prefix=/usr backup use-rel-suffix delete
current release=othersrc host=sup.netbsd.org hostbase=/ftp/pub base=/usr
	prefix=/usr backup use-rel-suffix delete
current release=allsrc host=sup.netbsd.org hostbase=/ftp/pub base=/usr
	prefix=/usr backup use-rel-suffix delete

Also, you might want to try dropping the -z, if nothing else works.
