- We have an industrial control SCADA system made by Square-D using a program
- called "Symax". The various remote sites communicate over phone lines at
- 2400BPS. The protocol is an 11-bit word (Not sure, but it appears to be
- start + 8 data + parity + 1 stop.) The dealer is trying to sell us
- Motorols 2440 modems at over $400 each, and claims that generic 2400BPS
- modems won't work due to the word size.
-
- Are they telling the truth, or just trying to sell us 2400 bps modems at
- a rather hefty price?
