Ronald,

I think USR is pulling your leg. All their string actually does is change &S1 to &S0 (which is the modem's default). The string they gave you is basically the same as the Lotus string only longer.

Issuing an AT&F followed by I4 and then an AT&F1 followed by I4 again using
TERMINAL reveals that only 5 settings differ between AT&F and AT&F1:

ATX4&F&A3&B1&H1&R2 and AT&F1 would be identical. The X7 command seems to be irrelevant. As far as I can tell, X7 simply enables ALL of the supported result codes, and is almost the same as X4.

This leaves &S1 (modem controls DSR) virtually the only difference between the Lotus and USR strings. Lotus seems to use the &S1 setting in nearly all of its modem strings but I don't recall that Router specifically requires it and the USR seems to work without it.

Let's ask Lotus: Why is &S1 needed? A better question might be why didn't USR just have you take out the &S1. You could have used the use "AT&F1" as you modem string.

Judith,
I had some trouble with this modem and am still having a little, though most of my 500 mobile users connect OK. I called US Robotics and they gave me a different string than cc:Mail recommends. Here is my old command line from cc:Mail remmed out and the new one from US Robotics.

@echo off
user
castoff all
call g:\dialbats\copyto 9
:restart
c:
cd \dialin9
:: router h:\ccmail com1 115200/lock modem/AT&F1&S1 list/99.9 LOG/f:dialin9.lst timeout/90 swap/EMS
router h:\ccmail com1 57600/lock modem/AT&F&A3&B1&H1&R2X7 list/99.9
LOG/f:dialin9.lst timeout/90 swap/EMS
if errorlevel 2 goto escape
copy f:alert.txt f:alert.msg
h:\ccmail\admin\import amscoinfosys sharon h:\ccmail @f:alert.msg call g:\dialbats\copyto 9 restart
nexttime 5
goto restart
:escape
f:


I still have occasional problems where it won't reset after a call and then it drops out of Router, hence the loop. Sometimes it actually goes through the loop several times before it will rest and sometimes i catch it and turn the modem off and on. I'm going to keep calling both cc:Mail and US Robotics util it works a LOT better.

A while ago there were quite a few messages going around about the US Robotics 28.8 modem. Needless to say I didn't need it then but do now.

Could someone send to me?

Thanks -- Judith
