Alan,
You may be able to do everything by just writing a streamDevice protocol
file. streamDevice can calculate a number of CRCs, it can build and
parse strings, etc.
For example, here is a simple protocol file for an Alcatel pressure gauge:
InTerminator = CR LF; ENQ = \005; ACK = \006;
readPressure { out "PR1\r\n"; in "\${ACK}"; out "\${ENQ}"; in "%*d, %f"; }
Mark, StreamDevice understands ACK and ENQ.
readPressure {
out "PR1\r\n";
in ACK;
out ENQ;
in "%*d, %f";
}
