Greetings,


	I am helping an organisation here in Omaha set-up a dial-up IP
network.  What we are looking for are terminal servers that support PPP as
well as SLIP.  They also need to have modem control (the Lantronix they have
right now uses the standard RJ-11 serial port implimentation, rulling out
harware flow control, and since SLIP and PPP need 8 bit clean paths, XON/XOFF
is also rulled out, making the use of compression modems that lock DTE speed 
and float DCE speed impossible - or am I missing something)?

	If anybody knows of a terminal server(s) that fit these requirements,
please e-mail me privately.  If there is interest, I will post a summary.  If
no current TS's support PPP, when  could we expect such support?

	Thank's in advance,
	-=Chris

SLIP may have problems over connections that feature XON/XOFF at some
part of the link.  With PPP, you can just OR 0x000A0000 into the
requested Async-Control-Character-Map, and any ^S or ^Q character in
the data stream will be transmogrified into a two-byte pair before
transmission, then returned to the normal single character upon
reception.

It's better to use RTS/CTS "hardware" flow control between your modems
and DTEs if you can, but XON/XOFF "software" flow control will work
well enough for PPP traffic.
