I forget the string commands to reset a USRobotics modem. Could anyone send me the commands. Thanks in advance.

Im not 100% sure if these work on the US Robotics Modems though I think I have used these same commands on them before.
Worth a try if your stuck.
When connecting Superhighway 56 External Modems to Meridian systems the following commands should be entered to ensure correct operation.
· Connect PC to modem with appropriate setting. Eg 9600 baud, 8,1,none
· Enter the following AT string
AT&F (Resets Modem to factory default)
AT&D0&K0&R1&S0&Y0 (&Y0 Ensures profile 0 is used on power up)
ATB0E0L2M1Q1V1X3Y0 (no output from modem)
AT S0=1 (Auto answer after 1 ring)
AT&W (Save settings)
· Connect modem and test.
· To view settings enter AT&V (It should look something like below)

Cables to connect to Meridian
· Option 11 Always connect remote access modem to port 0 where possible as certain functions can only be performed over this port. The 3 way - cable supplied with the option 11 is wired for modem connection so can connect straight in to the modem.
· Opt 51 to 81 There are various types of SDI card that you may come across but the ports should be wired out to a standard 25-way connector on the rear I/O panel. To extend this to a modem or terminal Nortel cable NT8D95 (various lengths) can be used or any standard 25 way cable. The SDI port needs to be strapped for DTE / DCE as required (see NTP’s for settings), or a Null Modem adapter may be required.
The exception to this is if an SDI paddle board is used. These are wired out to the I/O panel but are presented as none standard 9-way connections. Nortel cable NT8D93 is required to connect to a terminal or modem. Again the DTE / DCE needs setting as appropriate.
If a baud rate other than 9600 is required, ie1200 Bd try the following:
AT+MS=1,0,1200,1200

Nice reply Gareth. I've recently updated my Procomm Plus script to do all of the hard work for you..
Just copy & paste the data below into a *.was file, then compile it before using it.
; Programme to setup a U S Robotics 56K External Modem 15th November 2006
; These settings should work for a Meridian Option 11 - 81 TTY Port
; Do have "USER" = SCH only, as the TTY port could become disabled!.
;
; NOTE!
; This program will only work with a WINDOWS version of Procomm Plus.
; The " ; " denotes that the data on the program file line is ignored,
; when the script is run.

; Use ATS0=2 C/R (Number of rings for modem to answer = 2)
; (I've found that a minimum number of 2 rings is best!)
; Use ATM0 C/R (Speaker on modem = OFF & ATM1 = Speaker on until connected)
; Before you disconnect the line connection,
; Make sure that you are back into the Meridian SL1 program!.
; Also key "+++" first & wait until you get the "OK" prompt.
; (It takes you back to the modem!)
; If you don't do this,
; then the TTY port can disable it's self or the modem will lock up.
; How to configure the US Robotics 56K external Modem via a RS232 lead into your P.C.
; Key in the following …
; "AT&A3&B0&C1&D0&H1&I0&K0&M4&N6&R1&S0&T5&U0&Y1" C/R.
; The modem will answer with "OK"
; Followed by "ATB0E1F1L2M0Q0V1X4Y0" C/R.
; Enter the "S" Registers as shown in bold above. i.e.. "ATS0=2" C/R.
; Finally enter "AT&W0" C/R to store the data into memory.
; Power Modem "OFF" & "ON".
; The prompt "ATI4" C/R will list out the values stored in memory.
; To connect the Modem at 14400 baud rate & Meridian 1 TTY port at 19200 baud rate,
; Then use the settings "AT&N8" C/R followed by
; "AT&W0" C/R & power off & on the Modem again.
; You may want to check your pinouts. I made my own cable for our 61c using the following:
; DB25F - DB9F
; 2 - 2
; 3 - 6
; 4 - 4
; 5 - 9
; 6 - 8
; 7 - 3
; 8 - 1
; 20 - 7
; Make sure the TTY port on the paddle board (whatever type you are using is set up for modem. IE..DTC not DTE
; I've found that Option 11c TTY 1 & 2 Ports will need to have Pin 1 disconnected. It's the ground wire.

; The tests were carried out using "TTY 2" with "USER" = (SCH) ONLY! On a Option 11 system.
; NOTE!
; Do not have "USER" = (MTC,BUG,CTY, etc) as the TTY port could become disabled!.
; Also make sure that the standard TTY port settings are used i.e..
; "9600" baud rate word length = 8, 1 stop bit & no parity.

; Some other Notes!
; Use ATS0=2 C/R (Number of rings for modem to answer = 2)
; (I've found that a minimum number of 2 rings is best!)
; Use ATM0 C/R (Speaker on modem = OFF & ATM1 = Speaker on until connected)
; Before you disconnect the line connection,
; Make sure that you are back into the Meridian SL1 program!.
; Also key "+++" first & wait until you get the "OK" prompt.
; (It takes you back to the modem!)
; If you don't do this,
; then the TTY port can disable it's self or the modem will lock up.
; How to configure the US Robotics 56K external Modem via a RS232 lead into your P.C.
; Key in the following …
; "AT&A3&B0&C1&D0&H1&I0&K0&M4&N6&R1&S0&T5&U0&Y1" C/R.
; The modem will answer with "OK"
; Followed by "ATB0E1F1L2M0Q0V1X4Y0" C/R.
; Enter the "S" Registers as shown in bold above. i.e.. "ATS0=2" C/R.
; Finally enter "AT&W0" C/R to store the data into memory.
; Power Modem "OFF" & "ON".
; The prompt "ATI4" C/R will list out the values stored in memory.
; To connect the Modem at 14400 baud rate & Meridian 1 TTY port at 19200 baud rate,
; Then use the settings "AT&N8" C/R followed by
; "AT&W0" C/R & power off & on the Modem again.
; You may want to check your pinouts. I made my own cable for our 61c using the following:
; DB25F - DB9F
; 2 - 2
; 3 - 6
; 4 - 4
; 5 - 9
; 6 - 8
; 7 - 3
; 8 - 1
; 20 - 7
; Make sure the TTY port on the paddle board (whatever type you are using is set up for modem. IE..DTC not DTE
; I've found that Option 11c TTY 1 & 2 Ports will need to have Pin 1 disconnected. It's the ground wire.
