Tonight I started trying to control the NEC LT150 from my Win2k laptop.
I wrote a little java application to communicate over the serial port to the LT150. To test simple connectivity, I hardcoded the Version Request command. I was unsuccessful at getting a reply.
Next steps are:
1. Utilize a loopback connector so I can make sure the data is really going out the serial interface.
2. Once I've verified 1, the pin wiring on the cable becomes suspect. I purchased a DB9->DIN-DP8 connector for the MAC. The pin outs might not be the same. I have a diagram in the NEC manual.
3. Once I get connectivity going, I'll start processing interactive hex commands via System.in and start exploring.
Of course, if you have any helpful suggestions or comments, I welcome them.
