subject: REL vs ARQ connects

IS> Depends on the modem brand, but /REL usually refers to an MNP4 connect.
 IS> My DPX596, for example, returns /REL for MNP4, and /LAP-M for, well,
 IS> LAPM.

See my message to Stephen Lennie .. Netcomms aren't 'generic' in this respect.

 JP> With a NetComm M11F I always get 28800/REL/LAPM/V42BIS to
 JP> 3:712/816, but when
 JP> I crashmailed 3:711/401 a few weeks ago, I got CONNECT
 JP> 28800/REL/MNP/V42BIS.

MNP and V42BIS together look like a bit of a worry, unless you're talking
to an old Netcomm E5/M5 or Series 3 E7/M7, the ones that did BTLZ
compression over an MNP link - I'm pretty sure Trev doesn't run one of
those nowadays :)

As Bill said, not much to worry about so long as you get error-correction,
though it would pay to be sure to disallow MNP5 compression on mail calls.

Generic ..
 IS> Rockwell-based modems usually return /ARQ for both types of
 IS> error-correction, after another (optional) line with Protocol:
 IS> Alt (MNP4), or Protocol: Lap-M.

 JP> My modem rarely (if at all) reports an /ARQ connection
 JP> (with mail sessions).
 JP> Any idea as to why? If I remember correctly, I achieved
 JP> /ARQ connects when
 JP> I dialled into a BBS with my comms terminal ...

Sorry, don't know the Netcomm setup - could be the responses are selectable?
