+.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
+and no more retries of the command are permitted. After exceeding this
+value the program is terminated. Exception is \fB--receive\fP which is never
+quit after the initial initialisation has been successfuly negotiated.
+.TP
+.BR -r | --readtime\ < sec >
+Maximum response read timeout before command retry.
+.B mdsms
+sends the requested \fBAT\fP-style command to the device and expects response.
+After exceeding this time interval,
+.B mdsms
+reissues the last command until the maximum retry count (\fBmaxretry\fP) is exhausted.
+Standard value is
+.BR DEF_READTIME
+seconds and should be enough for standard
+.B mobiles
+responses. This is the only point where
+.B --send-mobildock
+differs the behaviour from regular
+.B --send
+option. Unfortunately when
+.B MobilDock
+has a voice call in progress, it will block any serial device
+communication with \fBSiemens A1\fP and it is impossible to differentiate between call-in-progress
+.B MobilDock
+and stucked/disconnected one, so the parameter
+.B readtime
+has very large value, see further. After exceeding this time interval,
+.B mdsms
+is terminated immediately,
+.B maxretry
+parameter notwithstanding. Standard value of this parameter is
+.BR DEF_READTIME_MOBILDOCK
+seconds and should be enough for any voice call.
