stuck in single-user mode

[William]

hi, i'm more or less a newbie to BSD administration. anyway, i forgot to close a quote on one of the lines in /etc/rc.conf. now the server on boots into single-user mode. problem is it won't let me edit the file so i can fix it. it goes into "read-only" mode. even if i could write to the file i can't seem to find vi or any other editor for that matter. any ideas on how i can get back into multi-user mode. all help is much appreciated. i'm running 4.4 current on an pentium III box.

thanks in advance
