[net.micro.cpm] Mainframe MODEMs

From:  John Mangrich <grich.uci@rand-relay>

  Has anyone ever made a list of implementations of the MODEM protocol on
mainframes that the authors are willing to share?  It's not too hard to find
the micro-end pieces, but the recent VMS question brought this point up.

  Thanks.

UNIX
	UMODEM, TMODEM, both available on MIT-MC CPM directory.

TOPS20
	MODEM.MAC	available from me.  Also on MIT-MC.  Currently
	 still having features added, so most recent version
	 (SRI-KL:<BILLW>MODEM.MAC) may be a little flakey.  As
	 far as I know, this is the only mainframe version that
	 supports CRCs.

VMS	FTPSEND, FTPGET	available from me.  doesnt work well.
	SRI-KL:<BillW.VMSMODEM>*.*

TENEX
	XMODEM.SAI	availble from MIT-MC

SEL-32
	MODEM.FOR	available from FJW.
	 I dont know whether this acyually works.

RT-11
	MODEM.C		available from somwhere. DECUS "C".

TOPS-10
	ASCSND.MAC	available fro me, but id have to get it off
	 of tape.  ASCII SEND from mainframe only.

ITS
	LMODEM (lisp?)	available at MIT.

Enjoy

I understand that MGORMAN@WSMR70A has modified UMODEM to work on
the BBN C/70.  I received some queries about that the other day, and
interested parties should contact him to see if he is willing to
supply a copy.

Actually, the current ITS version is MMODEM, and it supports CRC's.

LMODEM is still supported on ITS, also it works on Multics.  Source in
FJW;LMODEM > (although I think the running version on ITS is patched).
Yes, it's written in Lisp. Author is EB@MC.

Where can I find the specs of the MODEM program so I would know how
to add transfer protocol information to an existing communication
package so it could talk to MODEM?

The MODEM protocol is documented on MIT-MC in AR60:CPM;MODEM2 PROTOC
