| fredrick Tl Posts: 5 USA | Posted - 2/7/2001 12:51:51 AM     I have an old Courier x2 v.everything.US/Canada version. 25mhz speed I tried to flash it using sv25.xmd and Zterm. I am a mac user PPC7200/120 System 9.04 I have tried the usr support line to no avail. My Zterm program tells me that my modem firmware is corrupted and that firmware download is necessary. When I try the firmware update I get a comment that says: timeout on sector ack. What is that?Can I get the original firmware from usr? Is my modem toast? Please, Please help! modem firmware corrupted! |

Power the Courier off. 2. Set DIP switches 1, 5, and 10 on and 8 off. (For internal modems, 3. Power the Courier on. 4. Start your communications software package and send the operating 5. Power the Courier off. 6. Reset the DIP switches to their previous settings. 7. Power the Courier on.

| fredrick Tl Posts: 5 USA | Posted - 2/10/2001 9:33:06 AM Volor, Does this mean I send the same file sv25.xmd? I remember trying this procedure before but I still got the same message "firmware download necessary" and still remain unable to send any files to the modem. Is there some type of "original" firmware for the Courier v.everything X2? I will repeat the bootstrap downloader once again but if you or anyone have any more help I'd appreciate it. Should I get any favorable results, I will post it with bells and whistles on this most venerable forum. modem firmware corrupted! |
| Volor Tl Posts: 78 USA | Posted - 2/11/2001 3:12:10 AM Okay, here's what ya' do. Follow the procedure for the "Bootstrap Downloader" in my previous post, with one exception. Leave DIP Switch 8 set to "ON" for External Couriers, and 7 set to "ON" for internal. When you open your terminal program, type AT~X! And "C"s or other characters should start appearing onscreen. Send SV25.XMD through your terminal program to the Modem. When it finishes transferring the file, "OK" should appear (at the very least) in your terminal program. Then, complete the rest of the "Bootstrap Downloader" procedure in my first post. (Make sure you leave DIP Switch 7 for internal Modems and Dip Switch 8 for External Modems ALONE. They are to be left set to "ON" at ALL TIMES.) If this doesn't work, post again. There's supposed to be another procedure for recovering Couriers with corrupt firmware. I will try to locate it. Be aware that your Courier may be irreperably damaged if this post doesn't help you. |
| fredrick Tl Posts: 5 USA | Posted - 2/12/2001 1:03:58 AM Got it! I did an ATI7 and this is what I got: USRobotics Courier V.Everything Configuration Profile... Product type US/Canada External Supervisor date 03/13/98 Supervisor rev 7.3.14 Serial Number 21SZ29675R5V OK modem firmware corrupted! |
| Volor Tl Posts: 78 USA | Posted - 2/12/2001 4:02:11 AM The latest F/W Rev. is 3/13/98, so you've got it!  One thing I've noticed about Courier Modems is that their performance when downloading files & gaming online is if you limit the maximum speed to one level below what the Modem generally upshifts to. After a lengthy connection, check the ati6 diagnostics. Limit the maximum downstream possible by using &U &N. More information can be found here: http://808hi.com/56k/x2-linklimit.htm#3Com I can't explain to you how to do it on a Macintosh. I'm not associated intimately with Macintosh computers. You probably won't have to do this with your connection. I find it helps on low-quality phone lines. An example. I'm 20592FT from the local Verizon Central Office. I connect at 38,666bps. My Courier upshifts to 45,333, and the Modem exhibits packet loss and spiking latency. It also upshifts and downshifts CONSTANTLY (Around 150 times per hour). If I limit it to 44,000bps, I generally get a max of 60 BLERS per hour, and a max of 1 or 2 upshifts/downshifts. My download speed is also 5K/sec, whereas It's around 4.3 at 45,333. So you get the idea of how much this can help. |
