Attached is a text document that makes it easy to reset all of the modem settings via HyperTerminal.
At one point, I also played around with setting S19=01 (I am working off of memory on the S19 part), which had the effect of automatically resetting the modem after one minute. This might possibly help.
Dips 3 and 8 down.

AT commands to set internal registers for GEMS AVOS modems (US Robotics 33.6 fax modems) The following commands are structured to be easily pasted into the Hyperterminal window. This process facilitates setting the internal modem registers for GEMS modems used for AVOS uploads. After starting the Hyperterminal session on the port desired (See GEMS User's Guide, Appendix N), copy the AT commands one line at a time from below, and paste them into the Hyperterminal screen. After pasting each individual command into Hyperterminal, press the ENTER key to send the command to the modem. The modem should return OK after each command is sent. Once all commands have been sent to the modem, close Hyperterminal and turn off the modem. Then restart Hyperterminal and turn the modem back on. Then enter the ATI4 command and verify the changes are still there. NOTES: 1. Use the "Edit > Paste" menu sequence to paste the commands into Hyperterminal. I have experienced problems using "CTRL V" or "right click menus" to paste. 2. Do not click on the Hyperterminal screen below the menu. Clicking in the command area can confuse the system, it seems. 3. The &G0 setting is purposely left out as it causes problems. Verify that &G0 is correctly set, and if not, set it independently. 4. To ease the starting of Hyperterminal, paste a shortcut link to the Hyperterminal session onto the desktop. 5. To work on the next modem port, change the port selection in Hyperterminal, then shut down Hyperterminal and restart it. 6. The maximum command length is 58 characters. The modem does not count the AT prefix or spaces in this number. at commands: =============== AT B0 E1 F1 M1 Q0 V1 X4 Y0 &W AT &A3 &B1 &C1 &D2 &H1 &I0 &K1 &W AT &M4 &N0 &P0 &R2 &S0 &T5 &U0 &Y1 &W AT S00=1 S01=0 S02=43 S03=13 S04=10 S05=8 S06=2 &W AT S07=60 S08=2 S09=6 S10=14 S11=70 S12=50 S13=0 &W AT S15=0 S16=0 S18=0 S19=0 S21=10 S22=17 S23=19 &W AT S25=5 S27=0 S28=8 S29=20 S30=0 S31=128 S32=2 &W AT S33=0 S34=0 S35=0 S36=14 S38=0 S39=0 S41=0 S42=0 &W
