PROBLEMS with T3DIAL:

   There has been some confusion about the interpretation of the
ZCPR3 program error byte - whether zero means OK or BAD. Programs
I'm used to using (specifically the SLR assemblers) set the byte
zero for OK.

   T3DIAL, however, does the opposite.  For those who wish to
"fix" this problem:

     T3DIAL contains a routine at hex 198A to set the byte 0, and
a routine at 1992 to set the byte 'FF'.  To check your copy of
T3DIAL, note that these begin with:

		PUSH  AF
		set A to the value
		CALL 1ECF		; This sets the error byte
					; to the value in A

     If the remote computer was dialled correctly, location 101D
is reached.  This is currently: CALL 1992.  If there was an error
(user abort, no carrier, etc.), location 0FEF is reached.  This
is currently: CALL 198A.

     Therefore, to "fix" the problem, patch the program to
reverse the addresses in the two above calls.

     Note that, before any dialling is attempted, there is a CALL
1992 to set the error byte to 'FF'.  This might as well be left
in the place.  If T3DIAL terminates for any reason other than a
successful connection, I want the error byte ON.

another problem:

   Under some conditions (I haven't pinned this down), if I
specify a garbage name (like "XXXX") to dial, T3DIAL will not
kick me off but instead say "Dialing " followed by nothing, and
just hang.  I can abort with Ctl-C.
