[Nut-upsdev] MGE Pulsar ES 8+

[Rogenry Avila Batista]

Hi!

I have a MGE Pulsar ES 8+ UPS. Here is the response of some commands:

- Si   --> 3000 44 0
- Si 1 --> Pulsar ES8+ 0
- Ai   --> 5 0

It's not recognized very well by the current (from CVS) mge-utalk driver:

[root at srv01 ~]# /home/rog/src/nut/drivers/mge-utalk -i 20 -DDD -u root 
/dev/ttyS0
Network UPS Tools - MGE UPS SYSTEMS/U-Talk driver 0.86 (2.1.0)
debug level is '3'
UPS response to 30% Low Batt Level was ?
initups: OnDelay unavailable
initups: OffDelay unavailable
initinfo: 'Si 1' unavailable, switching to 'Si' command
initinfo: Si == >3000 44 0<
.
CAUTION : This is an older model. It may not support too much polling.
Please read man mge-utalk and use pollinterval
No model found by that model and version ID
Please contact us with UPS model, name and reminder info

As you can see, the driver said that the 'Si 1' command is unavailable 
and it can't get the output of the Syst Stat ('Ss') command.

Playing with the source code, I found that with a small wait before the 
command is sent, the driver works better:

static int mge_command(char *reply, int replylen, const char *fmt, ...)
{
         const char *p;
         char command[BUFFLEN];
         int bytes_sent = 0;
         int bytes_rcvd = 0;
         int ret;
         va_list ap;

         /* wait */
         usleep(100000);
...
...
...

}

Also, the UPS don't understand the 'Sm ?' and 'Sn ?' commands, but it do 
understand the 'Sm data' (Sm 20, for example) and 'Sn data' commands. 
So, replacing the following code in the function  upsdrv_initups(void):

bytes_rcvd = mge_command(buf, sizeof(buf), "Sm ?");
if(bytes_rcvd > 0 && buf[0] != '?') {
	mge_command(buf, sizeof(buf), "Sm %d",  mge_ups.OnDelay);
         if(strcmp(buf, "OK"))
                   upsdebugx(1, "UPS response to %d min ON delay was %s",
                                 mge_ups.OnDelay, buf);
} else
        upsdebugx(1, "initups: OnDelay unavailable");

bytes_rcvd = mge_command(buf, sizeof(buf), "Sn ?");
if(bytes_rcvd > 0 && buf[0] != '?') {
	mge_command(buf, sizeof(buf), "Sn %d",  mge_ups.OffDelay);
         if(strcmp(buf, "OK"))
                upsdebugx(1, "UPS response to %d min OFF delay was %s",
                                 mge_ups.OffDelay, buf);
} else
         upsdebugx(1, "initups: OffDelay unavailable");

with:

mge_command(buf, sizeof(buf), "Sm %d",  mge_ups.OnDelay);
if(strcmp(buf, "OK") == 0)
        upsdebugx(1, "UPS response to %d min ON delay was %s",
                                 mge_ups.OnDelay, buf);
else
        upsdebugx(1, "initups: OnDelay unavailable");

mge_command(buf, sizeof(buf), "Sn %d",  mge_ups.OffDelay);
if(strcmp(buf, "OK") == 0)
        upsdebugx(1, "UPS response to %d min OFF delay was %s",
                                 mge_ups.OffDelay, buf);
else
        upsdebugx(1, "initups: OffDelay unavailable");

the output is:

I don't know if the solutions above are right, or if I broke something 
else with them. I'll appreciate any comment of you, and I'll be very 
glad if someone of you points me to any place I have to look to get the 
mge-utalk driver work fine with this UPS model.

Best regards,

Rogenry.
