S1F65 instead of S1F13 for Connect Request.
The Equipment sends this message using the following format:
S1F65 W * H<-E
<L
<A MDLN>
<A SOFTREV>
> .
Format 1: The Host sends this message using the following format:
S1F65 W * H->E
<L> .
Format 2: The Equipment also accepts the following form of this message:
S1F65 W . * H->E
Either end of the link may send S1F65 as the first message to establish connection of the
link.

4.4 Stream 2
4.4.1 S2F13 - Equipment Constant Request
S2F13 W * H->E
<L
<U4 VID> * Equipment Constant ID
...
> .
The Host requests the VIDs of interest. Several VIDs can be specified if desired.
Normally, only VIDs of class EC (i.e. Equipment Constants) are used in this message.
However, any VID of class DV, EC, or SV can be used.
If S2F13 contains a zero-length list, then the Equipment will report all variables of class
EC, in order by VID.
For compatibility with older Host implementations, the Equipment allows the following
alternative form for this message, using an array format:
S2F13 W * H->E
<U4 VID VID ...> . * Equipment Constant ID
4.4.2 S2F14 - Equipment Constant Data
S2F14 * H<-E, Multiblock
<L
<V> * Equipment Constant Value
...
> .
The Equipment returns the Equipment Constants in the order requested in S2F13. If any
VID specified in S2F13 is invalid, the corresponding V in S2F14 has the following error
format:
<L> * V for Invalid VID
