- AZComm 1.00 is a modified version of the COMMunicator version 1.34
- AZComm contains 3 extra functions in the File menu , Zmodem Receive,
- Zmodem send, and Zmodem Resume Receive. the zmodem routines are the
- latest implementation and contain full-data streaming with 32-bit CRC
- error checking.
-
- these zmodem functions were coded for speed and are the ONLY routines
- for the Amiga that will send and receive with an ACTUAL throughput
- greater than 19,200 baud. new features include optional 7-wire serial
- handshaking and doublebuffered file writes at baud rates above 9600 to
- allow storage on slow devices.
-
- OPTIONS:
-
- 3/7-wire handshaking - to enable 7-wire handshaking , you must select the
- RTS/CTS gadget under the serial menu in preferences. if this is set in the
- current preferences , the serial device will be opened with the SERF_7WIRE
- flag set, otherwise only 3-wire handshaking will be used (Transmit, Receive,
- and Ground).
-
- xon/xoff - if you disable xon/xoff in the menu then during zmodem transfers,
- the serial device will be changed to accomodate SERF_RAD_BOOGIE. this is the
- fastest possible mode for the serial device to operate but will not allow
- for xon/xoff or parity checking. this usually isnt needed unless you expect
- transfers greater than about 16,000 baud throughput. xon/xoff is necessary
- if you are saving to a slow device (floppies) at high speeds or you will
- have overrun errors.
-
- zmodem send - selecting this item will open up the standard file requestor
- and ask you for the filenames to send. you can select 1 file from the
- requestor and that will be the first file sent. to send batch , you must
- seperate the file names by a space in the filename string gadget.
-
- zmodem receive - after selecting this menu you must select the output file
- path for the received files to be saved. only the pathname is used , any
- filename entered will be ignored.
-
- zmodem resume receive - same as zmodem receive , but if an incoming file
- already exists , it will attempt to resume the transfer from the end of
- that file.

- this is my attempt at bringing the Amiga 9600 modem community up to speed.
- Previously no terminal program could receive efficiently at baud rates
- above 9600.
