I am currently attempting to set up a SLIP/PPP server on a Linux box
(kernel 1.1.91) located within a university network. Access to the
network is provided by a Xyplex terminal server (14.4Kbps). The problem
I am encountering is that, for reasons beyond my understanding, there
are a few strange characters which do not pass properly through the
line. The details follow:
OUTGOING (from HOME->UNET) INCOMING (from UNET->HOME)
Hex Dec Char Hex Dec Char
--- --- ---- --- --- ----
*1 00 0 *4 0D 13 ^M ???
*2 11 17 ^Q 11 17 ^Q
*2 13 19 ^S 13 19 ^S
*3 8F 143
*3 9B 155
*1 -- This only occurred on occasion; but "on occasion" means ESCape
it out in my book.
*2 -- Understandable, as it's the usual flow control characters CTRL-Q
*3 -- These are the little *s that are screwing me to high
heaven. They're not in the control character block, and most
protocols can't seem to escape out anything THAT high. This is
the reason I have not had success with PPP, Twinsock (for long
periods of time), or almost anything else.
*4 -- This one just confuses me completely, but ok.
Anyone out there who has experienced a similar problem, and better yet,
knows a workaround, I'm all ears. I would like to use a method which
permits assigning an IP address to the calling system, and although I
know programs like TERM are nice for Linux-to-Linux connections, I would
prefer, if at all possible, to use a protocol such as PPP or SLIP so
that the hook-ins are OS independent.
Thanks in advance for any information. It is much appreciated.
Either a post or a direct reply would be great.
P.S. Ain't Linux grand?
