We just put two of the AcceleportRAS 8 cards into a Windows 2003 server. I have an application that dials out to remote devices to collect data. Some of the devices are on line sharing systems. We can connect fine, except to the ones that require us to wait for a secondary dial tone (the 'w' dial modifier). For example, a phone number like this:
atdt15555551212w,22,22,22,22
will fail to connect. It should dial the number, wait for secondary dial tone, then dial the line sharing code. I've tried dialing through HyperTerminal and it does the same thing. It works fine through other modems though. It's almost like the digi modem is ignoring the s7 register's value (which is set to 120). It dials the number, waits just a couple of seconds, then displays 'NO DIAL TONE'. Nowhere near the 120 seconds it should be waiting.
Anybody else experience this?
