+.B escape \fIxx,yy,...
+Specifies that certain characters should be escaped on transmission
+(regardless of whether the peer requests them to be escaped with its
+async control character map). The characters to be escaped are
+specified as a list of hex numbers separated by commas. Note that
+almost any character can be specified for the \fBescape\fR option,
+unlike the \fBasyncmap\fR option which only allows control characters
+to be specified. The characters which may not be escaped are those
+with hex values 0x20 - 0x3f or 0x5e.
