[comp.protocols.tcp-ip.ibmpc] NCSA Telnet with SLIP

roy@flinders.cs.flinders.oz (Roy McDougall) (03/05/91)

I am having trouble configuring NCSA Telnet 2.3 on a Toshiba T3100e laptop
to work with the SLIP8250 driver.  The documentation seems somewhat confusing.
Do I need to invoke SLIP8250 in my autoexec.bat before firing up Telnet?  If so,
what driver entries need to go into CONFIG.TEL?  If not what is the appropriate
entry in CONFIG.TEL?  Any help would be greatly appreciated.  Email replies preferred.

I am having similar difficulties with NCSA Telnet and SLIP8250.  However, here
is a helpful response I received the other day:

In anyone has any answer to this difficulty, please speak up.  I have not been
able to get the two to run together to date.

As far as the configuration goes, your config.tel file must contain the
following entries:
  
  myip=BOOTP
  class=6 #for SLIP

along with the usual parameters to tell it what interrupt and address to use.

   I have been successful running NCSA Telnet as modified by Clarkson
University (available in pub/cutcp/v2.2-D on omnigate.clarkson.edu)
with the SLIP packet driver from Russ Nelson's collection. The relevant
section from my CONFIG.TEL is:

	hardware=packet
	address=0
	ioaddr=0x60

(The value for ioaddr is whatever interrupt you choose for the packet
driver.) And here's how I load the SLIP driver:

	slip8250 0x60 -h SLIP 0x3f8 9600

ie, to use COM1 at 9600 bps.
