ok, well it's me again... hurrah!
what have you actually applied the acl to? if you know what the acl is called then just run "sh run" in enable mode and see where the access list is being applied. then go into that interface or whatever it is and remove it.
Code:
password:xxxxxx
router>en <--- normal mode here
password:zzzzzzz
router#sh run <--- enable mode started here
Generating Configuration...
[snip...]
int FastEthernet1
ip access-list 123 <--- bit you're looking for
[...snip}
router#conf t <--- enter configuration mode
router(configure)#int FastEthernet1
router(configure int)#no ip access-list 123 <--- the line to remove with "no" infront of it
router(configure int)#exit
router#
something along those lines. if you're stuck paste the whole output of sh run here.
ios is lovely... embrace it!
btw if you're using console access under widows i *really* recommend using tuTTY (a puTTY fork) for serial port console access, much better than hypertrm.
