Subject: [LCG.KERMIT: msxhpx problems]

Took the new version of MSXHPX.ASM last night.  Unfortunately, in being
compatible with both the 110 and the PLUS, it develops several problems
on the plus.  In particular:

	1.  PORT 2 is set to AUX.  On the plus, this is not the INTERNAL
MODEM necessarily, but is the default modem set in the system configurator.  To 
insure that the internal modem is used, the PORT selection logic should select
COM3, not AUX.

	2.  All character output is being sent to the punch via MSDOS PUNOUT 
call.  This is slow, and, worse, will direct output to AUX even if the serial 
port is in use.

	3.  Minor points:  the program starts with even parity and 7 bit words.  
This causes chaos in every situation we tried.

Changes are shown below by giving at least one line before and after each 
change.  Would appreciate your forwarding to appropriate authority.

Also, leaving DTR on on the PLUS is not just a nuisance, it is deadly, since you 
also leave on the MODEM or SERIAL interface, which eats the battery at 
incredible rates.  I have attached to the end of this a short program to turn 
those off.  I run KERMIT on the plus from a command file KERMIT.BAT which 
contains the following:

	MSXHPX 1%
	MODEMOFF

This guarantees modem/serial port doesn't run down battery.

I just tried MS-Kermit 2.32/A for the HP-110 and ran into two problems.

1. Kermit reports a

	?Program internal error, recovering

   if a MSKERMIT.INI file is present.  The settings in MSKERMIT.INI
   seems to be read and interpreted correctly by Kermit though.

2. Using a 1200 baud modem on a relatively clean voice grade line
   the average effective baud rate when transferring text files is
   about 50 (<= that is no typo, I do mean 50 baud).  XMODEM file transfer
   works fine under the same conditions.

[From jrd - It's probably a bug since we have had little chance to test it.
Perhaps you would be willing to look at the beta version of the next release,
when it's ready this summer.]
