We are using 7530 G2's and 7535 G2's running D3/Pick coding through TekTerm. As we migrate to formless printing (using SDSI Unform), we are looking into options for signature capture. Our only real requirements are the ability to specify the image name and location. In-house development is unlikely, but not totally ruled out. We are open to open source or commercial software solutions. We were also wondering if TekTerm was 'touch-aware' and could maybe handle the input itself, with our own backend coding to capture the image. Thanks in advance for your help!
While I'm not the complete expert on TekTerm or D3/Pick - I think I can help...
While TekTerm is touch-sensitive, it's functionality is limited to moving to different fields (or more recently allowing the click of a push-button in TESS/9010t emulation). It does not have the ability to track the pixel-level movement of a pen or any way to communicate the resulting bit-map to the server application.
Essentially, because TekTerm provides the client-side terminal emulation, it is limited to the protocol of the emulation. In the case of D3/Pick - I believe that emulation is based on ANSI/Telnet.
My belief is that you will need a separate application to present a panel to capture the pen movement, create a bit-map and transfer the bit-map back to the server application.
This is fairly simple application from the signature capture part of the functionality - you just need to decide how that application will become the foreground window, and communicate with the server application. The "become the foreground window" could be as simple as pressing <Alt>-<Tab> on the device to having the signature capture application connect to the server application and wait for a packet that indicates it should become foreground. The "communicate with the server" could be as simple as FTP or HTTP call to upload the bit-map as contents.
I hope this gives you some ideas.
If you want more information or some leads on who could provide this application, let me know.
Thanks for the information, Bruce! We've contacted our Psion vendor, Ryzex, to see what they have to offer, and we've also put a few feelers out to people like Topaz. It's looking like we may end up moving to dedicated signing pads rather than using our scanners for the signature capture, but we'd still love any leads you could give us. Again, thank you for your time and information!
