MDrive - a novice in trouble

["James Rezende Piton" <james@lnls.br>]

Hello,

I am trying to adapt the motorExApp,
under motor-6-5, to try a MDrive motor
under EPICS.

I (un)commented the proper lines (I think
so) and got the binaries.

I chose basic_asyn_motor.db as my base.
I changed a line in the original
motor.substitutions - instead of C and
S (card/slot), I created PORT and ADDR, following
the basic_asyn_motor model, with L0 and 2 (the axis address
recorded and tested in my motor controller).

======== motor.substitutions ==========
file "$(MOTOR)/db/basic_asyn_motor.db"
{
pattern
{P,     N,  M,        DTYP,     PORT, ADDR, DESC,          EGU,      DIR,   
VELO,  VBAS,  ACCL,  BDST,  BVEL,  BACC,  MRES,  PREC,  DHLM,  DLLM,  INIT}
{IOC:,  1,  "m$(N)",  "MDrive", L0, 2, "motor $(N)",  degrees,  Pos,   
1,     .1,    .2,    0,     1,     .2,    0.01,  5,     100,   -100,  ""}
}

=======  basic_asyn_motor.db ========================

record(motor,"$(P)$(M)")
{
	field(DESC,"$(DESC)")
	field(DTYP,"$(DTYP)")
	field(DIR,"$(DIR)")
	field(VELO,"$(VELO)")
	field(VBAS,"$(VBAS)")
	field(ACCL,"$(ACCL)")
	field(BDST,"$(BDST)")
	field(BVEL,"$(BVEL)")
	field(BACC,"$(BACC)")
	field(OUT,"@asyn(\"$(PORT)\",$(ADDR))")
	field(MRES,"$(MRES)")
	field(PREC,"$(PREC)")
	field(EGU,"$(EGU)")
	field(DHLM,"$(DHLM)")
	field(DLLM,"$(DLLM)")
	field(INIT,"$(INIT)")
	field(TWV,"1")
}



My st.cmd.unix was correspondingly modified to
configure the USB-serial adapter and with

MDriveSetup(1, 10)

and

MDriveConfig(0, "L0")

Then I start IOC

[iocWithAsyn]# ../../bin/linux-x86/WithAsyn st.cmd.unix

I am not sure about the right asyn syntax, but
why that ``Can't set "IOC:m1.OUT" to "@asyn("L0", 2)"'' at all?

My USB adapter works and so does the motor communicate,
tested in the same SL system.

Thanks in advance for any tip!

Another question: why are there some examples with "grecord",
instead of "record"?
