Although EazyLink offers more features, Y-Modem file transfers can triple its maximum speed, achieving 3K/sec at 38400bps regardless of OZ version. This is because the Y-Modem implementation does not use the OZ serial driver.
Transferring the 256KB of OZ 4.7.1 ROM files will take around 1m25s - something that is an agonising order of magnitude slower on an unmodified Z88 constrained to 9600bps in Eazylink.
Z88 Setup
There are several ways to perform a Y-Modem transfer on the Z88, which will depend on OZ version. Remember to set the serial transmit and receive baud rates to 38400 in Panel.
OZ Version | Popdown | Method |
|---|---|---|
5.0 | Filer | Tab to select multiple files, send batch using <>SB, receive a batch into the current directory using <>RB |
4.5 - 4.7.1 | ImpExport | Y for Y-Modem, then C for CRC, then K for 1K block size. Wildcards are permitted for batch sending. |
2.2 - 4.4.1 | Y for Y-Modem, then C for CRC, then K for 1K block size. Wildcards are permitted for batch sending. |
Computer Setup
On computer side, the recommended software is WindTerm since it is free and is available for Windows, macOS, and Linux. Configure as follows:
