Hello All,
This new ROM-upgrade is of today freqable on my system (2:285/255.1
+31-13-4636984)
Put a statement in your FDNODE.CTL (or a similar file if you're using another
mailer then FrontDoor):
phone 2:285/255.1 31-13-4636984
phone 15:900/9414 31-13-4636984
When done, compile again the nodelist and you would be able to request files 
on
my system.
The following upgrades are available:
12014418.zip     SupraFAXModem V34 extern                (magic-name 
UPE1201)
12114418.zip     SupraFAXModem V34 intern                (magic-name 
UPI1211)
12914418.zip     SupraFAXModem V34 intern PNP            (magic-name 
UPI1291)
13314418.zip     SupraSONIC 336V+                        (magic-name 
UPSONIC)
336now.exe       WIN95-flasher v1.440-12 ROM
12014412.exe     SupraFAXModem V34 extern v1.440-12 ROM
*BE˙AWARE*
The 1.440-12 code must first be loaded in your modem before you can use this
beta ROM-upgrade !!!
 -= Changes between the Supra 288 1.440-17 and the 1.440-18 ROM Code =-
1)  In Synchronous Access Mode when an EM command was
    received the modem would switch to command mode and
    respond with "OK" without sending the EM response
    first.  It now sends the EM response prior to the
    "OK" response.
2)  When originating a call the modem will set the maximum
    projected data rate for the 3429 symbol rate to 33.6Kbps.
    This allows calls to USR modems to connect using the 3429
    symbol rate.
3)  The V.42bis code was optimized to improve the compression
    performance.
4)  When the country code is set to a non-US value Bell mode
    is disabled when the modem is reconfigured to a factory
    configuration.  (ie. &Fn sets B0 not B1 outside the US)
5)  The EQM thresholds that control rate renegotiations to
    higher rates were slightly decreased.  With the v1.440-17
    firmware some lines would ping/pong between a high and
    low data rate, reducing the fall forward threshold prevents
    this.
6)  When bit 5 of S192 is set the EQM connection thresholds
    are lowered, making the modem more conservative when
    choosing data rates.
7)  A problem with the datapump configuration during a V.34
    connection using the 3000 symbol rate at a data rate of
    26.4Kbps was fixed.
8)  A change was made to how MP sequences are transmitted during
    phase 4 of a V.34 connection.  This decreases the chance that
    the MP sequence will not be correctly received by the remote
    modem which causes the connection sequence to restart.
9)  The LAPM selective repeat feature (SREJ) is now enabled by
    default in all modems.
All, regards & take care,
Henk            (e-mail: henk.loosbroek@pi.net)   [PGP KeyID: 9032BB1D]
