I'm having trouble getting better than ~450cps throughput to another
Trailblazer in the states. I'm able to get ~1200cps to a site in England,
and ~800cps to another site in the states.
The system with the slow throughput is a standard Sun 3/80 running SunOS 4.1.
The modem is connected to serial port A. I've tried playing with a number
of S registers on the remote system, including S121, 120, & J6 S36 without
any success.
Can someone runnning a simular configuration please send me the contents of
their S registers (cmd: ATN?)
I'm currently not using any flow control. Could this be a problem?
Here are the current values from the "guilty" system:
E1 F1 M1 Q6 P V1 X1 Version BA4.00
S00=001 S01=000 S02=043 S03=013 S04=010 S05=008 S06=002 S07=120 S08=002 S09=006
S10=007 S11=070 S12=050
S45=255 S47=004 S48=000 S49=000
S50=000 S51=004 S52=002 S53=001 S54=000 S55=000 S56=017 S57=019 S58=000 S59=000
S60=000 S61=010 S62=003 S63=001 S64=000 S65=000 S66=001 S67=000 S68=255
S90=001 S91=000 S92=000 S95=000
S100=000 S101=000 S102=000 S104=000
S110=255 S111=030 S112=001
S120=012 S121=001
Thanks in advance!
