Use will permit screening of ; calls prior to the line being placed off-hook: if the ; calling number is blocked or does not appear in the file ; CALLID.DAT, the line will not be answered. ; ; One effective use would be on a line having both modem ; and FAX service. If the call is not from a known host, ; the modem will not pick up and the FAX or voice mail ; may connect instead. If this use is selected it will be ; necessary to set the FAX not to answer until sufficient ; time has elapsed after the first ring for the list of known ; numbers to be scanned and a decision made. ; ; CALLID makes use of two files CALLID.DAT, the repository ; of numbers to be answered in the format ;. ; The must contain all digits returned by the ; Caller-ID stream but the format is unimportant since all ; non-numeric characters will be stripped. Syntactically, ; (407)555-1212 is the same as 407.555.1212, 4075551212, or ; 407 555 1212. The second file CALLID.LOG is created or ; appended when the script executes and contains the information ; on calls attempted. ; ; For proper use as a PROCOMM "HOST" the HOST SETUP must be set ; to EXIT on completion. The only known problem at this time ; is the condition if an "approved" number calls the system ; and hangs up before a connection is made. In this case PROCOMM ; may "hang" in the HOST "waiting" mode and will answer the ; next call. This is a problem with the HOST mode that will require ; complete HOST emulation in the ASPECT file to correct (in work). ; ; Version History ; ; 0.71 (beta) 1 November 1992 Southern Bell/Supra FAX/Modem ; version, 1st issue. ; ; For more information contact the author at (407)352-6007 6-9 pm ; EST (no collect calls) or write to POB 1203, Windermere, FLA, ; 34786.
