Two serial questions
Posted: Sun Jan 11, 2004 12:10 pm
On to an alarm integration project....
1. I assume two hardware interfaces can't use the same COM port, so I'm wondering how I can get a device with the features of the Modem/Phone Status Module as well as the ability to send strings to the modem (like the generic serial interface allows). I'm probably missing something really simple here....
2. Probably missing something really simple here, too. I can control my security system via a phone by pressing *# when I hear a dial tone. I can't duplicate that action using the modem - I'm sending ATDTW*#, and I get the nice lady saying that the number can't be completed as dialed. If I try it via a phone hooked up to the same phone line, it works. I've played with putting pauses in different places, etc. Any suggestions?
The 2nd item doesn't seem to be an HB issue (can't get it to work with HyperTerm, either), but thought you or someone on this forum might have some insight.
Thanks.
