I'm having a problem using a USR Courier V.32 making a V.32 connection
with a Telebit T2500. In this case the T2500 is the remote and the USR
is local. Although, the two make the connection successfully, the
connection drops after a few minutes of heavy load, as it happens
with data mostly going from T2500->USR.
If I'm in MNP mode, the USR reports a "LD disconnect" otherwise I
just get a carrier drop. It appears the remote T2500 is causing the
drop either way.
If I substitute a T2000 for the USR as the local modem, and make a PEP
connection (to the same T2500) there is no problem. One way or another
I'm using hardware flow control all around.
Any ideas?

Your HST is sending the MNP command "LD" (Link Disconnect) to the T2500, which is complying by disconnecting. LD is a code used by MNP modems to tell the modem on the other end that the local modem wishes to disconnect. This prevents a modem hanging around waiting for the carrier to come back, or locking onto some phone company tone, etc. Anyway, a friend and I were having the exact same problems, and when he upgraded to the latest HST Dual Standard firmware, it went away. >-- >Ken Mandelberg | km@mathcs.emory.edu PREFERRED >Emory University | {rutgers,gatech}!emory!km UUCP >Dept of Math and CS | km@emory.bitnet NON-DOMAIN BITNET >Atlanta, GA 30322 | Phone: (404) 727-7963 -- UUCP: ...!rutgers!faatcrl!jimb Internet: jimb@faatcrl.UUCP Under brooding skys and watchful eyes On convulsive seas of false urgency We walk empty corridors in vain - "No Exit", Fate's Warning
