- I think it's the MNP5 compression, not the error correction that's causing
- the problem. If the host computer is only running at 2400 baud, it can't
- keep up with the compressed connection, and gaps result. The best solution
- would be to raise the baud rate at the host end to 4800 to actually take
- advantage of the compression.
-
- On the other hand, it's probably impossible to get the system people to
- change the port/modem parameters... so try disabling the MNP5 compression
- on the Scout with AT*E3. This will give you 'Auto reliable MNP4' (error
- correction), without MNP5 (compression).
