Okay, if you MUST use pulse dialing, you must set the command string parameters of the modem, that's all. Normally, people use "ATDT", then the number being dialed. AT = ATTENTION Command to the modem D = Dial command to the modem T = Use TONE method of dialing P = Use PULSE method of dialing So you would use; "ATDP", then the number being dialed. If you do this and it STILL dials using tone, you'll need to get a look in your modem manual - Most good modems have a series of dip-switches, and TONE/PULSE dial toggle is usually one of them. There also commands to save your preferred command parameters to the NVRAM of your modem - They vary from modem to modem, you'll need to cunsult your manual, or modem manufacturer's website.
