TEL (1) BDS C Users' Group TEL (1)
NAME NAME
tel - dumb terminal emulator with file transfer
SYNOPSIS SYNOPSIS
tel tel
DESCRIPTION DESCRIPTION
Tel is a considerably modified version of Telnet v2.3, as
distributed with v1.46 of the BDS C compiler. The following
features have been added:
(1) multiple files may be sent/received by one command
(2) directories may be listed
(3) the quit command hangs up a hayes smartmodem.
To accommodate these changes, some of the command names have
been changed.
This program uses a modem to emulate a dumb terminal.
Incoming data may be buffered in memory and written to disk,
data may be transmitted from disk to the modem, or files may
be formally transferred in a "checksum" mode with automatic
handshaking and buffering.
CAVEATS CAVEATS
This program was tested with v1.50 of the BDS C compiler
under CP/M 2.2. It should work with other versions of BDS C
and CP/M, but has not been tested.

WARNINGS WARNINGS
The checksum file transfer does not follow the XMODEM
protocol.
Variable baud rate support is present, but commented out.
Hardware-specific coding would be required to implement it.
BUGS BUGS
Tel assumes that the CP/M console is much faster than the
modem (e.g. a 1200+ baud console with a 300 baud modem).
NOTES NOTES
Requires local.c and files.c for link.
