Hi, I'm wondering if the upgrade to amigados 2.0 has anything to do with the intermittant failure of my modem: ie. not intializing properly, or sudden spewing garbage charactors onto my screen, or multiple errors when dl'ing and the list goes on… I have a penril datacom cadet 2400 modem and use jrcomm 1.02. If you've heard of similiar problems please let me know. Also when I call compuserve now I get a connect 1200 message eventhough I am connected at 2400. I don't understand why this is happening but since all my other hardware has needed upgraded roms since I got 2.0 maybe there is a connection? Thanks

Scott, No, the modem itself should continue to work. The version of the ROM has nothing to do with the modem. The new serial driver that comes with 2.04 may be corrupted (perhaps during the copy) or JRComm may have a problem with 2.04, but not the modem itself. Don

Scott, Oh…one more thing…the serial port is controlled by one of the 8520 CIA chips in your Amiga. When the ROM was replaced with the new ROM, it's possible that one of the 8520's got zapped and that's causing your problem. Don

Have you ever had problems with telephone line noise? Are you connecting to CIS throught a node like TELENET or to a CIS number? Check your RS232 Cable (25 PIN) Lastly, try a different terminal program. Hopefully you have a backup of JRComm. For the most part your problem sounds like a noisy telephone line. Here in Oklahoma we get that way after a rain. Rodger – via Whap!

Thanks for your reply Rodger, I am dialing direct to cis, also what should I look for on pin 25 of my cable. In addition, another aspect of my problem is that jr-comm will say it is dialing the number but the modem is not responding, then I will reboot and turn off and on the modem only to find that it dials properly, which strikes me as kind of strange…Goodbye…Scott

Scott — (I'm jumping in here uninvited but…) Modems seem to need careful initialization. Much software does not accurately initialize modems for use, especially after failed sessions and abrupt terminations…. powering a modem on and off is often necessary … exiting a comm program and re-entering it is often necessary … and I've even resorted to exiting program 1, firing up program 2, exiting it, and going back to program 1 in order to initialize the modem properly… (I'm thinking MS-DOS Crosstalk here…) Of course, one could always read the modem manual about what initialization strings are appropriate…and a week later you'd know a lot more than I do… — Eric A.
