Lee, I've sent you a fax of the HP50759A modem commands from the appendix of my copy of the "HP Support Link Users Manual". If it's any help in your obtaining a copy, my manual describes itself on the back of the title page as "Owner's Manual 82003700 Revision B - 9/15/90 - PAK HP50759A". The back cover contains the number "86000972". I don't see a standard book number (ISBN) anywhere.

I have no user manual for the modem, HP says none is available, and the Response Center claims to have no knowledge of the command set for it. I need to add some pauses to one of the dialing strings, but the double quote character (") used by the HP37212B modem seems to not work. Can anyone tell me what is the correct character to use? Would someone be willing to provide a copy of the command set by fax or e-mail? TIA, Lee Gunter HMO Oregon 503-375-4498 Internet: [log in to unmask] 503-588-4350 fax
