---------------------------------------------------- Courier I-Modem Xmodem SDL Notes ---------------------------------------------------- In order to better support users of non-DOS systems, the Courier I-Modem can now perform flash ROM updates via the Xmodem file transfer protocol found in most communications software. IE020104.XMP is the Xmodem mode flash data file. (This is the same firmware that is in the *.NAC and *.SDL files, but in a different format.) This is the file that you will send to the I-Modem in Xmodem mode. The file supplied with this release is for US/Canada external versions of the Courier I-Modem. 1) Go into a terminal application that supports the XMODEM file transfer protocol. 2) Set the port to the one the modem is on. 3) Type ATI7 and hit <enter/return>. 4) Make sure your Supervisor rev is 2.0.6 or later. If it is not, you need to get the latest released code from the Internet at ftp.usr.com/usr/dl05/ie020009.zip and install it on your modem using a DOS-based computer. Otherwise, follow the directions in INSTALL.TXT. ---------------------------------------------------- Sending New Firmware to the Courier using Xmodem SDL ---------------------------------------------------- 1. Start a communications software package, such as Quick Link II or MacComCenter. Adjust the settings, if necessary, so that you can send AT to the Courier and get an OK response. NOTE: If you are sending the file from a Macintosh computer, make sure that you do NOT transfer the file in MacBinary format. In MacComCenter, for example, select Setup -> File Transfer and under MacBinary options, select "Never MacBinary." 2. Type AT~X! <Enter>. The Courier will respond as follows: SDL Xmodem file transfer - (Y)es (N)o (T)est > Responding with 'Y' will begin the file transfer process; responding 'N' will abort the process and the modem will return to command mode. *********************************************************************** * * * Responding with 'T' will begin the file transfer process in a * * "safe test mode". Test mode will verify the operation of the file * * transfer process and the integrity of the .XMP flash data file, * * without actually erasing or re-burning the flash chip. * * * *********************************************************************** 3. Respond with 't' to start an integrity test of the XMP file, or 'y' to begin an actual update of the flash ROM. SDL Xmodem file transfer - (Y)es (N)o (T)est >t * Test Mode - Flash ROM will not be modified* Begin Xmodem file transfer now. CC The Courier I-Modem will begin sending 'C' characters which are used as part of the Xmodem protocol handshaking. You may now begin sending the IE020104.XMP file to the Courier I-Modem using the XMODEM-CRC or XMODEM-Checksum protocol in your communications software. 4. After completion of the file transfer, the modem will display a result message. at~x! SDL Xmodem file transfer - (Y)es (N)o (T)est >t Begin Xmodem file transfer now. CC SDL Xmodem file transfer completed. Calculating CRC... OK Resetting modem...OK Once you see the OK response to the Calculating CRC and Resetting modem messages, your software upgrade is complete, and the modem will reset and return to command mode. ---------------------------------------------------- IMPORTANT NOTE! ---------------------------------------------------- Many times new code will change the memory locations used by various registers. BE SURE TO ENTER THE FOLLOWING COMMAND AFTER UPGRADING!: AT&F1*P=0S67=0S68=1S69=0&W This will restore the factory default template, set S67 to 0 and write these changes to NVRAM. It will also enable the enhanced auto select and Turbo PPP features (S68). You may want to make a screen print of your current settings first (ATI4).
