This driver also support some newer models with backward UTalk compatibility, such as Pulsar Evolution and Pulsar EXtreme C\&. As these models also support the SHUT protocol, prefer mge\-shut for serial communication, or use the USB port, if available, with the usbhid\-ups driver\&.
.SH "EXTRA ARGUMENTS"
.sp
This driver supports the following optional settings in the \fBups.conf\fR(5):
.PP
\fBlowbatt\fR=\fInum\fR
.RS 4
Set the low battery warning threshold at which shutdown is initiated by
\fBupsmon\fR(8)\&.
.sp
The factory default value is 30 (in percent), and can be settable depending on the exact model\&.
.RE
.PP
\fBoffdelay\fR=\fInum\fR
.RS 4
Set the timer before the UPS is turned off after the kill power command is sent (via the
\fB\-k\fR
switch)\&.
.sp
The default value is 20 (in seconds)\&.
.RE
.PP
\fBondelay\fR=\fInum\fR
.RS 4
Set the delay before the UPS is turned on, after the power returns\&.
.sp
The default value is 1 (in minutes)\&.
.RE
.PP
\fBoldmac\fR
.RS 4
Set this flag if you are running Linux on an Oldworld Macintosh box (all beige Apple Macintosh)\&. This might also be needed for other OSs (like *BSD) running on PowerMac\&.
.RE
.SH "KNOWN ISSUES"
.SS "Repetitive timeout and staleness"
.sp
Older models, such as ES/ESV ones, might report repetitive "data stale" errors\&. This is due to the fact that these models don\(cqt support too much polling\&. To solve this problem, add "pollinterval=20" in ups\&.conf, and change the value of MAXAGE to 25 in upsd\&.conf, and DEADTIME to 25 in upsmon\&.conf\&.
