Hi Eric,
at the moment, I don't have a direct support for this. But I tried the following
construct:
record (ai, "$(P):read")
{
    field(DTYP, "stream")
    field(INP,  "@proto read($(P):calc) terminal")
    field(FLNK, "$(P):calc")
}
record (calcout, "$(P):calc")
{
    field(CALC, "A*10^B")
    field(OUT, "$(P):read")
}
with the protocol
Terminator="\r\n";
read {
    in "U1";
    in "%(\$1.A)d%(\$1.B)d";
}

The protocol reads mantissa and exponent as decimal integer and put them into
fields A and B of a calc record. This record calculates the value and writes it
back to the input record.
I already got a request for the same format earlier but have not yet found the
time to implement it.

Hello!
I've run into a problem I'm guessing others have solved using the
Streams module.  I have a device that outputs reads in the format:
U1\r\n+00011-01\r\n
meaning 11e-01 , which would be the preferred format for using a
general format specifier in the protocol file.
What would be the format to successfully read in this number from the
Streams protocol file?
(Or, will I have to run as a string read through a c filter program,
sub record)
Thank you!
Eric
