可用来与串口设备通信，如调试交换机和Modem等。它的Debian软件包的名称就叫minicom，

The file selector is designed to be very intuitive. It should nearly always do the expected thing. So a minimal amount of explanation is all that should be necessary. (If I did it right.) Minicom's current working directory is changed to whatever directory is displayed on the selector's title bar. Double-tapping the space-bar (taps within a second or so of each other) while on a directory entry will move you into that directory. The "Goto" requester will always initialize to whatever is configured for the default upload/download directory, as appropriate. If blank: the user's HOME directory is where it'll go to. The first time the selector is entered, it will go to the default download or upload directory--depending on which was called-up: an upload or a download. Subsequent invocations of the selector will result in it coming-up in whichever directory it was last--dependent on whether uploading or downloading. (Doing "Goto" <ret> will easily get you to the default directory for the operation, as noted above.) When the selector's display is constrained by a wild-card pattern via the "Show" menu selection, moving to a new directory will result in a full display again. This was intentional. But the pattern is remembered, so simply doing "Show" <ret> will re-invoke the filter. I felt this would be less confusing. The functions at the bottom of the selector are: Goto - Go to a particular directory Prev - Go to previous directory Show - Limit display to (wildcard) pattern Tag - Tag files with (wildcard) pattern Untag - Untag files with (wildcard) pattern Okay - All done The functions at the bottom of the selector ("Goto", etc.) are hot- keyed on their first letter. Right-left cursor motion works on them as well. If "selectable download directory" enabled (zmodem, ymodem, etc.): For downloads where the filenames are determined by the protocol (e.g.: zmodem): files will appear in the selector, but attempts to tag them are a no-op. (Nothing happens.) You select the desired download directory by entering it.
