+.BR -m | --maxretry\ < # >
+Maximum retries of any \fBAT\fP-style command during the session. All the
+retries are summed during one run of
+.B mdsms

+Maximum response read timeout before give up.
+.B mdsms
+sends the requested \fBAT\fP-style command to
+.B MobilDock
+and expects response. Unfortunately when the voice call is in progress,
+.B MobilDock
+will block any serial device communication and it is impossible to differentiate
+between calling
+.B MobilDock
+and stucked/disconnected one. After exceeding this time interval,
+.B mdsms
+is terminated immediately,
+.B maxretry
+parameter notwithstanding. Standard value is
+.BR DEF_READTIME
+seconds and should be enough for any voice call.
