**<- squished bugs
There seems to be a major problem with the 2.9BSD implementation of uucico
on 1200 baud lines talking to 2 different 2.9BSD systems we're only getting:
With ucla-an (09/27-15:25) total data 294648 bytes 12924 secs = 22.80 CPS
With ucla-an (09/27-15:25) recieved data 0 bytes 0 secs
With ucla-an (09/27-15:25) sent data 294648 bytes 12924 secs = 22.80 CPS
With ucla-ci (09/27-15:25) total data 1874341 bytes 85608 secs = 21.89 CPS
With ucla-ci (09/27-15:25) recieved data 4422 bytes 279 secs = 15.85 CPS
With ucla-ci (09/27-15:25) sent data 1869919 bytes 85329 secs = 21.91 CPS
Typically with other systems (V7, sysIII, 4.xBSD, and Locus) that I
talk to at 1200 baud the Gross Xfer rate is ~100 CPS. Even the V7
system that I talk to at 300 baud is faster (~27 CPS).
Has anyone else seen this problem? If so are there any fixes available?
Please respond directly to me, I'll post a summary (and any fixes that we
discover) to the net.
Thanks in advance.
