Dennis,
I was able to print out documentation for a certain Zoltrix AT Command Manual for Voice commands. Thanks for the web lead.That may or may not be useful in this context.
I got an "OK" response from the "ATI7" command, so I am still in luck. =)Ouch. That does not bode well. I would have expected something much more meaningful than "OK". Do as I suggested previously - test this modem outside of VFP. Try Control Panel | Modems | Diagnostics at the minimum.
So executing the "AT#VLS", "AT#VBT" et al commands must depend on having the "AT#CLS=8" command return "OK" or else issuing them would be useless?That fairly well covers it, yes. Try going
here and see if a manual is avalable for your model modem.
PS I believe I am 12 hours ahead of you right?Or 13? Look
here.
