So Far, I've gathered the following (not completely verifed) information:
UART 16550 is a good number. Though, it needs some help, specially on
Windows systems, so that compressed (high speed) data caracters gets to the
program that required them before they got "overrun".
COMxFiFo=1 setup a FIFO buffer for input caracters.
The setup I have is:
;; Add-Ons for smart Comms
;ReflectDOSInt2A=0
;TimerCriticalSection=0
;OverlappedIO=on
;PSPIncrement=5
;UniqueDOSPSP=TRUE
;Com2AutoAssign=2
Com2Base=02F8 ; hardware specific
Com2Irq=3 ; hardware specific
Com2Fifo=1
Com2TxSize=8
Com2RxSize=16
Com2RxTrigger=4
Com2buffer=1500
ComBoostTime=20
;InDOSPolling=FALSE
;DMABufferSize=64
;NoEmmDriver=ON
;EmmExclude=A000-FFF
Int28Critical=off
TrapTimerPorts=0
SyncTime=0
RMMTimeout=0
Had to change my comm.drv & serial.386 too.
You bet I don't understand any of those lines.
Less "overruns", no more "drop carrier", but don't quote me on this.

We add similar trouble, and we did :
- update logintimeout from 10 to 30
(30 seconds to wait for the "Login:" string).
- Even better: Don't use "Login:" "Password:" checkup, but PAP
(Password Authentication Protocol) for PPP users.
- If at all possible, make sure login scripts don't look for
"Login:" "Password:" strings, but rather "ogin:" and "assword:" strings.
- For users with dynamic IP address, check the IP address "proposed"
by the PC to the portmaster is 0.0.0.0
- Trace the connexion and look for differences between the speed setup
before modem connexion ... and the speed setup (PC - modem) after the
modems have connected (but that was mostly a cure for "garbage"
caracters at login).
Tell us if any of those hints did the job.
Sincerely,
Eric
