- I have a few questions concerning the capabilities of the
- Best Data Products Smart One Fax/Modem (9624FQ), with regards to
- CCITT standards.
-
- This modem is described as a 9600/4800 bps SEND/RECEIVE FAX &
- 2400/1200/300 bps DATA MODEM.
-
- Technical information:
-
- Compatability: Data Modem Standards:
- CCITT V.22bis 2400 bps
- CCITT V.22 1200 bps
- Bell 212A 1200 bps
- Bell 103 0-300 bps
-
- Send/Receive Fax Modem Standards:
- CCITT Group III send/receive
- Fax format CCITT T.30 and T.4
- CCITT V.29 at 9600 bps with fall back to 7200 bps
- CCITT V.27ter send & receive at 4800, 2400 bps
- CCITT V.21 Channel-2 send & receive at 300 bps
- EIA-578 Service Class 1 Commands
-
- Error Correction: CCITT V.42, MNP 2-4
- Supported through the Rockwell RPI driver
-
- Data Compression: CCITT V.42bis and MNP level 5
- Supported through the Rockwell RPI driver
-
-
- What I would like to know is if this modem is capable of a higher data
- baud rate by using MNP 5. There is no mention of turning on MNP 5
- in any of the registers.
- And what does 'Supported through the Rockwell RPI driver' mean?
- Does that mean this 'driver' is a software driver?
- If this thing can talk to fax machines at 9600 baud, then why can't it
- talk to other 9600 baud modems (or other modems of the same make at
- 9600 baud)????
-
- Who knows the real scoop on these 9600/2400 baud fax/modems.???
