Reaching back into my old BBS days....... .... If you read/write directly to the COM port a modem is attached to, you can send an "ATDT" command. If there is no dialtone, you should get a "NO DIALTONE" response quickly (5 seconds). If there IS dialtone, you will most likely get a NO CARRIER response after the timeout.
... And I think the timeout register is S7. So to something like this: ATS7=3 ATDT Should give you a response in 3 seconds or so... -Tom -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of gene Martinez Sent: Tuesday, November 09, 2004 11:36 AM To: [EMAIL PROTECTED] Subject: [SA-list] RE:dial tone Is anyone using salive to check for dial tone on a line. if so how??
