| Disable |
Uses no error correction (EC) or data compression. No
flow control; modem-to-modem (DCE) and computer-to-modem (DTE) rates must
match. |
| Normal |
Normal connection uses flow control; DTE rate and DCE
rates may differ. |
| MNP4 |
Microcom Networking Protocol - Class 4: Configures
the modem to use error correction by resending blocks of data that are
corrupted during transmission. Uses hardware flow control. |
| MNP5 |
Configures the modem to use an advanced data
compression protocol that increases throughput by up to 200% (a 2-to-1
compression ratio). Includes error correction (MNP Classes 2-4) and hardware
flow control. |
| V.42 |
International standard for data error correction.
Uses LAP-M (Link Access Procedure for Modems) as the primary error-control
protocol and MNP Classes 1-4 as backup protocols. Uses hardware flow
control. |
| V.42BIS |
International standard for data compression and
decompression. Increases throughput by up to 400% (a 4-to-1 compression
ratio). Always uses V.42 error correction and hardware flow control. |
| Software Flow Control |
Your communications software will set the parameters
for aspects of your PC Card's performance. |
| Hardware Flow Control |
Your PC Card and it's firmware will set the
parameters for aspects of your PC Card's performance. |
