i am in need of some desperate help.
i just started for a small security installation / service company.
we are trying to set up existing panels with external (US Robotics ) modems. the company is driving from site to site to update card databases ect. i think i have the physical setup correct.

2 56k modems at each end (with correct dip settings according to honeywell tech support) connected by a db-9 to db-25 serial cable on each side.

i entered the strings that honeywell tech told me to use.

&A0&k0S2=128 <---computer end

does anyone have any insight on this?
