recovered from an error condition found when hanging up the modem via hardware
command by lowering DTR (data terminal ready).
The log is a standard text file that can be viewed by choosing Connection
Advanced from
the modem’s properties dialog box and then clicking the View Log button in the Advanced Connection
Settings dialog box that opens (see Figure 25.9).
Following is a sample log file that shows the preliminary handshake with the modem. This
identifies the information file (INF) that is used, in addition to the status of connections, error
control, compression, and hang-up characteristics. Note that in this case, the modem did not
respond to the lowering of DTR for the hang-up and was disconnected with software. This
might indicate a configuration problem with the modem; however, it is benign in this case.
