24 | /* The E7000 is an in-circuit emulator for the Hitachi H8/300-H and | |
25 | Hitachi-SH processor. It has serial port and a lan port. | |
26 | ||
27 | The monitor command set makes it difficult to load large ammounts of | |
28 | data over the lan without using ftp - so try not to issue load | |
29 | commands when communicating over ethernet; use the ftpload command. | |
30 | ||
31 | The monitor pauses for a second when dumping srecords to the serial | |
32 | line too, so we use a slower per byte mechanism but without the | |
33 | startup overhead. Even so, it's pretty slow... */ | |
