The remote device only has 3 wires, TX, RX & COM, so HW flow control is out. I,ve strapped pins 4, 5 & 6 and 8 & 20. The device sends binary data, so SW flow control is out. I've turned off result codes and echo, but am still getting corrupted data. The remote device works directly connected to a laptop. I'm tired of standing outside in the snow trying to coax this thing into working. Any ideas would be appreciated. Don How are you establishing the connection? Are you dialing into the USR remote modem with a computer/modem, or is this a fixed always on connection? What is the cable configuration when you have the laptop hooked up direct to the remote collection device? A laptop or computer serial port is a DTE device, while modems are DCE devices, and as such, require TXD and RXD to be swapped when going from one to the other. Need more info to give any suggestions. Good luck.Art,I am always dialing into the USR modem from the host site, there are adozen or so remote sites that will get polled regularily. The cable fromthe modem unplugs and connects to the laptop via a null modem, a F-Fgender changer, a 25 to 9 pin adapter and a 25 pin M-F LED port monitor,although not in that particular order. The pin swapping is proper, I amgetting data from the remote device, actually, I'm getting not only thecorrect data, but erroneous data on top of the correct data. The I4 dumpfrom the modem looks like this:U.S. Robotics 33600 Fax Settings...B0 E0 F0 M1 Q1 V1 X4 Y0BAUD=9600 PARITY=N WORDLEN=8DIAL=TONE ON HOOK CID=0&A3 &B1 &C0 &D0 &G0 &H1 &I0 &K1&M4 &N6 &P0 &R2 &S0 &T5 &U0 &Y1S00=001 S01=000 S02=043 S03=013 S04=010 S05=008 S06=004S07=020 S08=002 S09=006 S10=014 S11=070 S12=050 S13=000S15=000 S16=000 S18=000 S19=000 S21=010 S22=017 S23=019S25=005 S27=000 S28=008 S29=020 S30=000 S31=128 S32=002S33=000 S34=000 S35=000 S36=014 S38=000 S39=000 S40=001S41=000 S42=000SW 1-8 NFFNFNFN (N=ON=Down, F=OFF=Up)I an considering changing F0 to F1, the echo back to the device might becreating the problem. I am also looking into changing the &N and &Usetting to allow connections from 300 to 9600 baud. None of thesechanges, possible with the exception of the F0 to F1 should affect thedata stream.Any thoughts?Don
