Here's an awk script I wrote to munge the configuration output of my
Trailblazer T2500's so that I could more easily restore a config (when
doing rom upgrades, for example). My awk is vanilla SunOS 3.5.
Typically, I tell the modem:
atz1
atn?
atz2
atn?
And then slurp up the output and stick it on a file. To setup a modem
as per the configuration stored in the file, I run the awk script over
it and stuff the commands at the modem.
It assumes you have new enough roms such that registers that are
different than the factory defaults are identified with a colon (e.g.
"S51:005").
If you add any features, I'd appreciate getting a copy (but if you
convert it to perl, please do not send it to me because I DON'T LIKE
SPAM!)
