[comp.dcom.modems] Problems with T2500 UUCP throughput

mju@mudos.ann-arbor.mi.us (Marc Unangst) (10/03/90)

My T2500 is having some problems with UUCP 'g' throughput.  Even
though UUCP spoofing is enabled on the connection (I get "CONNECT
FAST/UUCP"), I'm only getting around 515cps, instead of the
1200-1300cps that everybody else is bragging about.  For a UUCP
program, I'm running Waffle v1.63 on an 8MHz XT clone, with the
Opus!Comm FOSSIL driver, and the communications port locked at
19.2Kbps.  (Yes, I have a NS16550AFN UART on that port.)  Here's the
T2500's NVRAM config:

atn?
E1 F1 M1 Q0 T V1 W0 X3 Y0 &P0 &T4     Version GF7.00-T2500SA
S00:000 S01=000 S02=043 S03=013 S04=010 S05=008 S06=002 S07=040 S08=002 S09=006
S10=007 S11:050 S12=050 S18=000 S25=005 S26=000 S38=000 
S41=000 S45=000 S47=004 S48=000 S49=000 
S50=000 S51:005 S52:004 S54:002 S55=000 S56=017 S57=019 S58:002 S59=000 
S61:045 S62=003 S63=001 S64=000 S65=000 S66:001 S67=000 S68=255 S69=000 
S90=000 S91=000 S92=000 S93=008 S94=001 S95:002 S96=001 S97:001 S98=003 
S100=000 S101=000 S102=000 S104=000 S105=001 S106:001 S107=020 
S110=255 S111:030 S112=001 
S121=000 S130=002 S131:001 
S150=000 S151=004 S152=001 S153=001 S154=000 S155=000 S157=000 S158=000 
S160=010 S161=020 S162=002 S163=003 S164=007 S169=000 S255=000 
OK

Is there something really obvious that I'm missing here, or is my
machine just not fast enough to handle that kind of speed?

Do you talk about news or other pre-compressed stuff? In this case
you need to turn off the online compression of the T2500. You can
do this by setting S96=0 (for MNP), S98=0 (for V.42) and S110=0
(for PEP). Usually, these registers are set by the UUCP dialers
script when you dial out to another site. For UUCP dial-ins the
remote site has to take care that compression is off.
