Os9 kermit (Glen Seaton/Robert Larson/James Jones) (01/26/86) (ral)
Compilation warnings:
Use the switches defined in os9ker.hlp to configure for your system.
Compilation on a coco takes 165 pages of free memory, and takes about
40 min. on a stock system.
Single sided disk users will have to move the documentation, etc.
elsewhere to have enough room for the .r files.
Known bugs:
Server functions were not completely correct when I got them. I tried to
fix the get and quit functions, but not the actual host server mode. Use
server functions with caution.
Timeout interval is unstable and incorrect. I did not consider this a
problem worth worrying about. It does do timeouts reliably and with no
system dependent code. (Except a few compile time constants.)
Messages should go to stderr rather than stdout.
Connect mode on a Coco bit banger port has been reported to be unreliable.
The problems is the bit banger port uses more than 90% of the cpu time to
receive characters at full speed, so insufficent time is left to display them
one at a time. I have modified the os9con.c routine to do multi-character
i/o if the sgstat routine returns the number of characters available. It
would be nice if someone could contribute an interupt driven /t1 driver
that does this. (possilbly based on the public domain one in the os9 users
group library.) Note this has yet to be tested on a coco.
Spelling in documentation, messages and comments may be incorrect.
Still untested:
Os9 system acting as host, especially in server mode.
Desired features:
Speed setting of external line. (Use xmode or tmode currently.)
Simple single compile switches for systems other that COCO.
More server functions, for both host and guest modes.
8-bit quoting.
Make overlap a function of the device being written to. (I.e. QT+ needs it
for floppy but not ramdisk or hard disk.)
