[comp.sys.ibm.pc] MS Kermit 3.0 problem with DSZ

caf@omen.UUCP (WA7KGX) (01/23/90)

The "push" command (^[p) in MS-Kermit 3.00 sends an XOFF character to
the modem before calling DOS.

Using this to activate DSZ's term mode with a "dsz t" command
causes most remote hosts to freeze.  The remote host can be
unfrozen by keyboarding Ctrl-Q in DSZ's terminal mode.

Since there has been some discussion about file transfer speeds
lately, I ran some tests as long as I had MS-Kermit set up.

Kermit transfers used 8 bit CRC, ZMODEM used 32 bit CRC.
Times were measured with a stopwatch.  Your results may vary.
